| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2026-126955 | Medium | 2026-11-13 | Not applicable | No public exploit | Glance from 0.8.0 before 0.8.8 contains an observable response discrepancy in handlePageRequest and handlePageContentRequest that allows unauthenticated attackers to enumerate configured page slugs. Attackers can request candidate names against /{page} or /api/pages/{page}/content/ and compare 303/401 versus 404 status codes to discover hidden page names. |
| CVE-2026-105671 | Medium | 2026-11-13 | Not applicable | No public exploit | The login flow in Zenitel Connect before 1.11.0 returns different error responses depending on whether a submitted username exists, which allows remote attackers to enumerate valid user accounts via crafted login requests. |
| CVE-2026-68512 | Medium | 2026-11-11 | Not applicable | Proof of concept only | Paaster is a pastebin application. Prior to version 3.3.0, Paaster's account login has no rate limiting, lockout, or CAPTCHA of any kind, and a companion endpoint openly discloses whether a username exists along with that account's password-hashing salts. Together these let an attacker enumerate real accounts and then brute-force their passwords with unlimited, unthrottled attempts. This issue has been patched in version 3.3.0. |
| CVE-2026-124432 | Medium | 2026-11-08 | Not applicable | Proof of concept only | phpMyFAQ 4.1.9 before 4.1.11 and 4.2.0 pre-releases before 4.2.0-beta.3 contain an account enumeration vulnerability in the unauthenticated POST /api/webauthn/prepare-login endpoint, which returns stable stored credential IDs for passkey-registered accounts but an md5(time())-derived fallback ID otherwise. Unauthenticated attackers can compare allowCredentials IDs from requests sent more than one second apart, without rate limiting, to identify existing passkey-registered accounts and their credential IDs. |
| CVE-2026-17202 | Medium | 2026-11-07 | Not applicable | No public exploit | IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to enumerate usernames due to observable differences in response behavior. |
| CVE-2026-100362 | Medium | 2026-11-05 | Not applicable | No public exploit | SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the /legacy/Api/V8/OAuth2 password-grant endpoint returns distinct error messages for an invalid username and an invalid password. An unauthenticated remote attacker can use those response differences to enumerate valid CRM usernames and target confirmed accounts with password spraying, credential stuffing, brute-force, or social-engineering attacks. This issue is fixed in versions 7.15.2 and 8.10.2. |
| CVE-2026-97702 | Medium | 2026-11-04 | Not applicable | Proof of concept only | Open edX Platform enables the authoring and delivery of online learning at any scale. From the Ulmo release until release/ulmo.4 and release/verawood.1, the GET /api/support/v1/manage_course_team/ endpoint in CourseTeamManageAPIView requires only IsAuthenticated and omits the global support-role authorization check intended for this help-desk surface. Any authenticated learner can supply an email, username, or user_id for an arbitrary target and use the 200 and 404 response discrepancy to distinguish an active account from an absent or inactive account. A caller with a course-level or organization-level instructor role can additionally obtain the target user's staff or instructor assignments within the caller's course or organization scope. Anonymous callers remain blocked, and the separately authorized PUT behavior is outside this vulnerability. This issue is fixed in release/ulmo.4 and release/verawood.1. |
| CVE-2026-122139 | Medium | 2026-11-04 | Not applicable | No public exploit | blueprintUE Self-Hosted Edition before 4.3.3 contains an account enumeration vulnerability in ForgotPasswordMiddleware.php that allows unauthenticated attackers to identify registered email addresses. Attackers can compare password reset redirect targets for submitted emails, and failed lookups are never rate-limited, enabling unlimited enumeration attempts. |
| CVE-2026-119700 | Medium | 2026-10-30 | Not applicable | No public exploit | WPGraphQL before 2.24.2 contains an information disclosure vulnerability that allows unauthenticated attackers to determine object existence through distinct error responses. Attackers can iterate IDs against deleteMediaItem, updateMediaItem, deleteComment and updateComment mutations to discover hidden draft, private, trashed posts, custom post types, and unapproved comments. |
| CVE-2026-49442 | Medium | 2026-10-23 | Not applicable | Proof of concept only | Cacti is an open source performance and fault management framework. Prior to version 1.2.31, a User Enumeration vulnerability allows an attacker to identify valid usernames on the Cacti service. When a user attempts to log in, the application returns slightly different error messages depending on whether the provided username exists in the system. When username exists on Cacti, in the response, they see Access Denied! Login failed. When it does not exist on Cacti, they see Access Denied! Login Failed. The only difference between the responses is the capitalization of the letter "f" in the word failed. This issue has been patched in version 1.2.31. |
| CVE-2024-7478 | Medium | 2026-10-21 | Not applicable | No public exploit | When a WSO2 product is configured to use an external user store, the system fails to adequately obscure the existence or validity of usernames during authentication attempts. This oversight allows an attacker to repeatedly query the authentication mechanism with different username guesses, enabling the enumeration of valid usernames present in the external user store. The discovery of valid usernames can increase the risk of targeted brute-force attacks, social engineering, and information leakage. Attackers can leverage this information to craft more convincing phishing campaigns or other social engineering tactics to trick users into revealing sensitive data. The presence of username enumeration could also negatively impact an organization's reputation, leading to loss of customer trust, regulatory non-compliance, and potential legal and financial repercussions. |
| CVE-2026-111056 | Medium | 2026-10-19 | Not applicable | No public exploit | FOSSBilling is an open source billing and client-management platform. From 0.1.0 until 0.8.7, the unauthenticated POST /api/guest/client/create endpoint reveals whether a submitted email belongs to a registered client because guest signup returns a distinct unredacted error when the submitted email already exists. The trigger is an unauthenticated request to POST /api/guest/client/create with a target email address. An attacker can compare the guest-signup response for a target email to determine whether the email belongs to an existing FOSSBilling client. Box\Mod\Client\Api\Guest::create returns the error after Client\Service::clientAlreadyExists finds a matching record, and the API response exposes that exception message without redaction. This issue is fixed in version 0.8.7. |
| CVE-2026-111887 | Medium | 2026-10-17 | Not applicable | Proof of concept only | phpMyFAQ before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains an account enumeration vulnerability that allows unauthenticated attackers to confirm registered display names and emails via a distinct HTTP 409 response. Attackers can submit guest comments to the comment create endpoint with candidate user and mail values to link names to emails for targeted phishing. |
| CVE-2026-111386 | Medium | 2026-10-16 | Not applicable | Proof of concept only | Nezha from 1.7.0 before 2.3.15 contains an information disclosure vulnerability that allows authenticated members to enumerate other tenants' server IDs through differential responses. Attackers can sweep sequential IDs against getServerConfig and setServerConfig, distinguishing 'permission denied' from success payloads to map other users' servers. |
| CVE-2026-105664 | Medium | 2026-10-16 | Not applicable | No public exploit | The endpoint exposes an observable response discrepancy when processing ID values. A request submitted with a nonexistent ID returns a distinct error response code from one submitted with a valid, registered ID, allowing an attacker holding a valid access token - but without further authentication or authorization - to distinguish valid ID values from the full 10-digit numeric search space. Combined with the absence of meaningful rate limiting on this endpoint, this discrepancy constitutes an enumeration oracle, enabling an attacker to discover registered devices at scale. |
| CVE-2026-110310 | Medium | 2026-10-14 | Not applicable | No public exploit | A remote user who can read encrypted objects in the S3 bucket can force a padding downgrade by altering the padding scheme recorded in an object's metadata to legacy PKCS#1 v1.5. Since this padding scheme is susceptible to the well-known Bleichenbacher attack, the user can use a PKCS#1 v1.5 padding oracle to recover the RSA-wrapped envelope key and decrypt the object. To remediate this issue, we recommend that users upgrade to version 3.2.2 or 4.0.3. The 1.x and 2.x lines will not be patched, users of those lines need to migrate to 3.2.2 or 4.0.3. |
| CVE-2026-109206 | Medium | 2026-10-12 | Not applicable | No public exploit | LogicalDOC Community Edition through 9.3 contains a username enumeration vulnerability that allows unauthenticated attackers to identify valid accounts because the AvatarServlet (/avatar) performs no session validation. Attackers can supply usernames or numeric IDs in the userId parameter and compare 1x1 transparent images against real avatars to enumerate users and retrieve profile pictures. |
| CVE-2026-107843 | Medium | 2026-10-09 | Not applicable | No public exploit | Contao is an Open Source CMS. From version 4.1.0 until 5.3.50 and 5.7.12, ModuleRegistration::compile() enters its follow-up registration branch on any POST to a page containing the registration module without verifying FORM_SUBMIT or the preceding captcha result. resendActivationMail() can then invoke OptInToken::send() without rate limiting, allowing an unauthenticated attacker to cause repeated activation emails to be sent to an address with a pending registration and to determine whether that pending registration exists. The branch is reachable only when reg_activate is enabled and the target has an unconfirmed registration and opt-in token. This issue is fixed in versions 5.3.50 and 5.7.12. |
| CVE-2026-59785 | Medium | 2026-10-05 | Not applicable | No public exploit | Host search in Frontend allows filtering by fields that are not displayed, including stored IPMI and PSK credentials. A user with read access can guess a credential and see from the search result whether the guess was right, letting them uncover it. |
| CVE-2026-82043 | Medium | 2026-10-02 | Not applicable | No public exploit | UTMStack before 11.2.16 contains an account enumeration vulnerability that allows unauthenticated attackers to determine registered email addresses by observing differing HTTP responses from the POST /api/account/reset-password/init endpoint. Attackers can submit arbitrary email addresses and distinguish registered accounts, which return 200 OK, from unregistered accounts, which trigger a 500 Internal Server Error with backend error details, enabling targeted phishing or credential attacks. |
| CVE-2026-86778 | Medium | 2026-09-30 | Not applicable | No public exploit | Observable response discrepancy vulnerability in Maksisoft Technology, IT, and Software Industry and Trade Inc. Maksisoft Gym allows Account Footprinting. This issue affects Maksisoft Gym: from 0.5.10 before 0.5.11. |
| CVE-2026-84717 | Medium | 2026-09-23 | Not applicable | No public exploit | A flaw was found in the Ansible Automation Platform automation-controller. The unauthenticated Bitbucket Data Center webhook receiver skips HMAC signature verification for diagnostics:ping events after it has already looked up the target template, causing the endpoint to return HTTP 200 for a template that has a Bitbucket DC webhook configured and HTTP 403 otherwise. An unauthenticated remote attacker can use this response discrepancy as an oracle to enumerate which Job Template and Workflow Job Template IDs have Bitbucket DC webhooks configured, without knowing the secret webhook_key. |
| CVE-2026-71462 | Medium | 2026-09-23 | Not applicable | No public exploit | StringListPathField.to_internal_value() calls os.path.exists() on unbounded user-supplied paths. 200 vs 400 response reveals existence of arbitrary absolute paths on the controller-web pod. Tenant superuser can confirm /etc/tower/SECRET_KEY, k8s service-account token, receptor sockets, ConfigMap mount points. Mainly impactful on managed AAP (ansiblecloud.com) where tenant admin != host admin. |
| CVE-2026-71458 | Medium | 2026-09-23 | Not applicable | No public exploit | URLModificationMiddleware resolves named-URL lookups against unfiltered Model.objects before RBAC. The 403→404 shim only rewrites 403 responses, leaving the pk=0 miss path with a different 404 detail string. Differential "Not found." vs "No <Model> matches..." reveals whether a named resource (org, credential, inventory, host) exists anywhere on the platform. Enables cross-tenant internal hostname enumeration. |
| CVE-2026-89173 | Medium | 2026-09-11 | Not applicable | No public exploit | Smart Video Intercom System developed by Kingdom Communication Associated has a Sensitive Data Exposure vulnerability. Unauthenticated remote attackers can enumerate valid user accounts by exploiting differences in system responses. |
| CVE-2026-9161 | Medium | 2026-09-10 | Not applicable | No public exploit | Observable response discrepancy vulnerability in DernekPlus Website Template allows Account Footprinting. This issue affects Website Template: through 10092026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. |
| CVE-2026-78584 | Medium | 2026-09-02 | Not applicable | No public exploit | Observable Response Discrepancy (CWE-204) in the Kibana Osquery feature can lead to information disclosure via Query System for Information (CAPEC-54). An authenticated user holding Osquery live-query privileges could determine whether a scheduled query identifier exists in a Kibana space they are not authorized to access. |
| CVE-2026-81033 | Medium | 2026-08-26 | Not applicable | No public exploit | Automatisch reveals whether an address is registered through the response to its forgot-password request. The controller at packages/backend/src/controllers/internal/api/v1/users/forgot-password.js looks the address up and chains a not-found throw onto the query, so an address with no account raises an error that the global handler renders as a not-found status, while a registered address proceeds to send the reset message and returns no-content. The route is mounted without authentication. Submitting candidate addresses and comparing the two status codes therefore establishes which addresses hold accounts, with no credential and no rate limiting in the path. |
| CVE-2026-75575 | Medium | 2026-08-25 | Not applicable | No public exploit | Rocket.Chat exposes the sendForgotPasswordEmail Meteor method without a DDP rate limit, so an unauthenticated caller may invoke it as often as it likes. The method is reachable over DDP and over the HTTP route POST /api/v1/method.callAnon/sendForgotPasswordEmail, and it triggers a password reset message for any address that matches an account. With no DDPRateLimiter rule registered for it, a caller can drive an unbounded volume of reset mail at a chosen address from the deployment's own mail sender, and can probe addresses at scale: the method answers true for an address with no account and for a successful send, but false when the address belongs to an account that authenticates through an external provider and Accounts_AllowPasswordChangeForOAuthUsers is off, so repeated calls distinguish that class of account. Later versions register a rule permitting ten calls per minute per client address. |
| CVE-2026-66002 | Medium | 2026-08-20 | Not applicable | No public exploit | Frappe is a full-stack web application framework. Prior to 15.115.0 and 16.27.0, the public request-data web form and PersonalDataDownloadRequest class in frappe/website/doctype/personal_data_download_request/personal_data_download_request.py return distinguishable response shapes for registered and unregistered email addresses, including the user_name field and persistence behavior. A remote attacker can compare the responses to enumerate registered users. This issue is fixed in versions 15.115.0 and 16.27.0. |
| CVE-2026-54739 | Medium | 2026-08-19 | Not applicable | No public exploit | Lemmy is a link aggregator and forum for the fediverse. Prior to 0.19.19 and 1.0.0-beta.1, Lemmy's login endpoint in crates/api/api/src/local_user/login.rs returns different errors depending on whether the username_or_email value exists. LocalUserView::find_by_email_or_name propagates a NotFound response for an unknown account, while an existing account with a wrong password returns LemmyErrorType::IncorrectLogin. This observable response discrepancy, including HTTP 404 for a nonexistent account and HTTP 400 for an incorrect password on an existing account, allows an unauthenticated attacker to confirm registered usernames or email addresses and use the results for targeted credential attacks or social engineering. This issue is fixed in versions 0.19.19 and 1.0.0-beta.1. |
| CVE-2026-14672 | Medium | 2026-08-13 | Not applicable | No public exploit | Observable response discrepancy in PostgreSQL SCRAM authentication allows an unauthenticated user to test the existence of a user via observing the SCRAM iteration count. This requires the probed user to have a non-default scram_iterations count, because the authentication challenge for a nonexistent user reports the default scram_iterations. Within major versions 16-18, minor versions before PostgreSQL 18.6, 17.11, and 16.15 are affected. Versions before PostgreSQL 16 are unaffected. |
| CVE-2026-73306 | Medium | 2026-08-12 | Not applicable | Proof of concept only | Budibase is an open-source low-code platform. Prior to 3.39.25, POST /api/global/auth/:tenantId/login incremented the failure counter in packages/worker/src/api/controllers/global/auth.ts only for existing users, while packages/worker/src/middleware/emailLockout.ts returned X-Account-Locked and Retry-After only for locked identifiers. An unauthenticated attacker could compare the response after repeated failures to enumerate valid email addresses and temporarily lock valid accounts. This issue is fixed in version 3.39.25. |
| CVE-2026-72588 | Medium | 2026-08-10 | Not applicable | No public exploit | A user enumeration vulnerability in bluewave-labs/Checkmate through 2.1.0 allows an unauthenticated remote attacker to determine whether a given email address is registered. The POST /api/v1/auth/recovery/request endpoint returns HTTP 200 for registered email addresses and a different status code for unregistered ones, enabling attackers to enumerate valid user accounts. |
| CVE-2026-55998 | Medium | 2026-08-05 | Not applicable | No public exploit | The endpoint /v3/import/{token}_{clusterId}.yaml retrieves the cluster object before validating the token. When a valid cluster ID references a cluster that has private registry secrets configured, a nil pointer dereference in pkg/systemtemplate/private_registry.go causes the request to return HTTP 502 Bad Gateway. For cluster IDs that do not exist, the endpoint returns HTTP 200. This observable difference in response codes constitutes a reliable enumeration oracle. |
| CVE-2026-14202 | Medium | 2026-08-04 | Not applicable | No public exploit | Observable response discrepancy vulnerability in Bilin Software and Informatics Consultancy Inc. HUMANIST Digital Human Resources allows Account Footprinting. This issue affects HUMANIST Digital Human Resources: from 26.0 before 26.1. |
| CVE-2026-54768 | Medium | 2026-07-31 | Not applicable | Proof of concept only | WPGraphQL provides a GraphQL API for WordPress sites. From 2.0.0 until 2.15.1, the deprecated user field on SendPasswordResetEmailPayload lets an unauthenticated caller distinguish existing author-class accounts through the sendPasswordResetEmail mutation and obtain public profile fields. This issue is fixed in version 2.15.1. |
| CVE-2026-42218 | Medium | 2026-07-20 | Not applicable | No public exploit | xrdp is an open source RDP server. Versions 0.10.6 and prior contain a timing side-channel vulnerability in the login interface. Due to a discrepancy in response processing times, a remote attacker can infer the existence of a username on the system, leading to unauthorized information disclosure via username enumeration. This issue has been fixed in version 0.10.6.1. |
| CVE-2024-23574 | Medium | 2026-07-17 | Not applicable | No public exploit | HCL Aftermarket EPC is vulnerable to attack since It was found that a malicious actor can use brute-force techniques to either guess or confirm valid users in the system. Use renumeration is when a malicious actor can use brute-force techniques to either guess or confirm valid users in a system |
| CVE-2026-47083 | Medium | 2026-07-16 | Not applicable | No public exploit | An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is an ESEARCH cross-user content oracle. By using the ESEARCH command, an authenticated IMAP user could enumerate folder names under any account they could name. Search would return UIDs of messages matching the search, creating a content oracle (without allowing arbitrary reads of the target's content). |
| CVE-2026-61503 | Medium | 2026-07-13 | Not applicable | No public exploit | Rejetto HFS 3.0.0 through 3.2.0 returns observably different responses from its login endpoint depending on whether the submitted username exists. A remote unauthenticated attacker can use this to confirm valid account names, including the default admin account, facilitating password-guessing and session-forgery attacks. |
| CVE-2026-53908 | Medium | 2026-07-01 | Not applicable | No public exploit | MCO is vulnerable to User Enumeration through authentication-related functionalities. The application returns distinguishable responses for valid and invalid users during username reminder and password reset operations. An attacker can leverage these differences to enumerate valid usernames and email addresses. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions. |
| CVE-2026-53947 | Medium | 2026-06-24 | Not applicable | No public exploit | Ghost is a Node.js content management system. From 5.18.0 until 6.21.1, a discrepancy in responses from the members signin endpoints made it possible for an unauthenticated attacker to determine whether a given email address belongs to a registered member of a Ghost site. This vulnerability is fixed in 6.21.1. |
| CVE-2026-54445 | Medium | 2026-06-17 | Not applicable | No public exploit | vantage6 is an open-source infrastructure for privacy preserving analysis. Versions prior to 5.0.0 provide an initial user with username `root` and password `root`. This is not ideal because attackers know that almost all vantage6 servers have a user with username `root` that probably has admin rights, and the initial password is very weak and it is possible that administrators forget to reset it. Version 5.0.0 fixes the issue. As a workaround, it is possible to delete the `root` user after it has been used to create other users. |
| CVE-2026-43926 | Medium | 2026-06-04 | Not applicable | No public exploit | FOSSBilling is a free, open-source billing and client management system. Prior to version 0.8.0, the password reset confirmation endpoint `/client/reset-password-confirm/:hash` is handled by a non-API controller and is not covered by FOSSBilling's rate limiter, which only applies to `/api/*` routes. This allows an attacker to probe the endpoint for valid reset tokens without any per-IP request limiting, attempt counting, or lockout mechanism. The endpoint acts as an oracle, returning a distinguishable response for valid versus invalid tokens (HTTP 200 vs HTTP 302 redirect). An attacker can submit unlimited token guesses to the password reset confirmation endpoint with no throttling applied. However, practical exploitability is significantly mitigated by the current token generation, which uses `hash('sha256', random_bytes(32))`, providing 256 bits of entropy. Tokens also expire after 15 minutes and are deleted after successful use. The same architectural gap applies to other controller-served auth routes, including `/staff/email/:hash` (admin password reset confirmation) and `/client/confirm-email/:hash` (email confirmation). Version 0.8.0 fixes the issue. Some workarounds are available. Configure a reverse proxy (e.g., Nginx, Apache, Cloudflare) to apply per-IP rate limiting to the `/client/reset-password-confirm/*` and `/staff/email/*` paths and/or use a WAF rule to limit request rates to these endpoints. |
| CVE-2026-45620 | Medium | 2026-05-29 | Not applicable | No public exploit | WWBN AVideo is an open source video platform. In 29.0 and earlier, objects/mention.json.php has no User::loginCheck() or admin gate. It only has an entry guard: preg_match('/^@/', $_REQUEST['term']) and hard-coded rowCount=10. This enables unauthenticated user enumeration. |
| CVE-2026-45294 | Medium | 2026-05-29 | Not applicable | Proof of concept only | FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to 1.8.219, the password reset endpoint returns visually distinct responses depending on whether the submitted email address belongs to an existing user account, allowing unauthenticated attackers to enumerate valid helpdesk agent email addresses. This vulnerability is fixed in 1.8.219. |
| CVE-2026-44306 | Medium | 2026-05-12 | Not applicable | No public exploit | Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.21 and 6.15.0, responses from the forgot password forms hinted at whether an account existed for a given email address. An unauthenticated attacker could use this to enumerate valid users, which can aid in follow-up credential-based attacks. This vulnerability is fixed in 5.73.21 and 6.15.0. |
| CVE-2024-0391 | Medium | 2026-05-11 | No exploit published | No public exploit | The check user account lock states feature within the email OTP flow fails to validate user input, allowing an attacker to infer the existence of registered user accounts. The discovery of valid usernames can increase the risk of brute-force and social engineering attacks. Attackers can leverage this information to craft targeted phishing campaigns or other malicious activities aimed at tricking users into divulging sensitive data, potentially damaging the organization's reputation and leading to regulatory non-compliance and financial consequences. |
| CVE-2026-20195 | Medium | 2026-05-06 | Outside Waratek scope | No public exploit | A vulnerability in an identity management API endpoint of Cisco ISE could allow an unauthenticated, remote attacker to enumerate valid user accounts on an affected device. This vulnerability exists because error messages are observed when the affected API endpoint is called. An attacker could exploit this vulnerability by sending a series of crafted requests to the affected endpoint and analyzing the differentiated responses. A successful exploit could allow the attacker to compile a list of valid usernames on an affected system. |
| CVE-2026-34319 | Medium | 2026-04-21 | Not applicable | No public exploit | Vulnerability in the MySQL Shell product of Oracle MySQL (component: Shell: Core Client). Supported versions that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where MySQL Shell executes to compromise MySQL Shell. Successful attacks require human interaction from a person other than the attacker.

| CVE-2026-24468 | Medium | 2026-04-20 | Not applicable | Proof of concept only | OpenAEV is an open source platform allowing organizations to plan, schedule and conduct cyber adversary simulation campaign and tests. Starting in version 1.11.0 and prior to version 2.0.13, the /api/reset endpoint behaves differently depending on whether the supplied username exists in the system. When a non-existent email is provided in the login parameter, the endpoint returns an HTTP 400 response (Bad Request). When a valid email is supplied, the endpoint responds with HTTP 200. This difference in server responses creates an observable discrepancy that allows an attacker to reliably determine which emails are registered in the application. By automating requests with a list of possible email addresses, an attacker can quickly build a list of valid accounts without any authentication. The endpoint should return a consistent response regardless of whether the username exists in order to prevent account enumeration. Version 2.0.13 fixes this issue. |
| CVE-2026-40485 | Medium | 2026-04-18 | Not applicable | Proof of concept only | ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the public API login endpoint (/api/public/user/login) returns distinguishable HTTP response codes based on whether a username exists: 404 for non-existent users and 401 for valid users with incorrect passwords.
