CVE Severity Published▾ Status Exploitation Description
CVE-2026-117624 High 2026-10-28 Protected by Waratek No public exploit Jenkins 2.587 and earlier, LTS 2.580.1 and earlier does not consistently enforce the restriction on deserializing objects of types marked as storing their configuration in independent top-level configuration files as nested values, allowing attackers to bypass the root element check and potentially inject nested objects.
CVE-2026-117620 High 2026-10-28 No exploit published No public exploit Jenkins 2.587 and earlier, LTS 2.580.1 and earlier allows attackers with Overall/Read permission to trigger warnings in the "Manage Old Data" feature that can be acted on by administrators to inject attacker-controlled data, overriding existing user account information, including login passwords.
CVE-2026-117619 High 2026-10-28 No exploit published No public exploit Jenkins 2.587 and earlier, LTS 2.580.1 and earlier allows requests authenticated using HTTP Basic authentication, including with an API token, to obtain a "remember me" cookie, allowing attackers who have obtained a user's API token to retain access to Jenkins using a "remember me" cookie after the API token is revoked or expires.
CVE-2026-117618 High 2026-10-28 No exploit published No public exploit In Jenkins 2.587 and earlier, LTS 2.580.1 and earlier, the HTTP endpoint for creating the first user account does not check whether the setup wizard has been completed, resulting in a race condition that allows unauthenticated attackers to create an administrator account while the initial user account is being replaced.
CVE-2026-117617 High 2026-10-28 No exploit published No public exploit Jenkins 2.587 and earlier, LTS 2.580.1 and earlier checks for symbolic links in the path of an extracted file only before creating its parent directories, not immediately before writing it, and allows symbolic links in artifacts to replace existing files or empty directories, allowing attackers with Item/Configure permission to write files to arbitrary locations on the Jenkins controller file system.
CVE-2026-117616 High 2026-10-28 Protected by Waratek No public exploit Jenkins 2.587 and earlier, LTS 2.580.1 and earlier provides an HTTP endpoint that loads agents by name without validating the name, allowing attackers with Overall/Read permission to load any config.xml file on the controller file system as an agent configuration, and to overwrite an arbitrary config.xml file when that agent is saved, potentially resulting in arbitrary code execution.
CVE-2026-117614 High 2026-10-28 No exploit published No public exploit Jenkins 2.587 and earlier, LTS 2.580.1 and earlier converts the launch commands in older agent configurations into launchers provided by the Command Agent Launcher Plugin without checking whether they have been approved by an administrator, allowing attackers with Agent/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM.
CVE-2026-117612 High 2026-10-28 No exploit published No public exploit Jenkins 2.587 and earlier, LTS 2.580.1 and earlier does not apply its deserialization filter to classes referenced by the `resolves-to` attribute during XStream deserialization.
CVE-2026-84652 High 2026-09-02 No exploit published No public exploit In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, Jenkins does not rotate the session when a user is authenticated via the "remember me" cookie, allowing attackers able to serve content on the same site as Jenkins to set a known session cookie in the victim's browser, which after the victim authenticates via the "remember me" cookie, grants the attacker access to Jenkins as that user.
CVE-2026-84650 High 2026-09-02 Protected by Waratek No public exploit In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, transient fields cannot be excluded from deserialization, allowing attackers able to submit configuration updates to specify the values of transient fields that will be deserialized, the impact depending on how those fields are used.
CVE-2026-84648 High 2026-09-02 No exploit published No public exploit In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the system log viewer does not escape log record metadata (source, level, and timestamp) resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers in control of agent processes.
CVE-2026-84645 High 2026-09-02 No exploit published No public exploit In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, objects of types marked as storing their configuration in independent top-level configuration files in Jenkins (such as the global configuration and jobs) can appear as nested field values in user-submitted `config.xml` documents and subsequently handle HTTP requests via Stapler, resulting in remote code execution.
CVE-2026-70429 High 2026-08-05 No exploit published No public exploit Jenkins 2.575 and earlier, LTS 2.568.1 and earlier handles case-insensitivity in user names and group names inconsistently, allowing attackers able to create new users or groups with names that case-insensitively match other characters to impersonate other users or be granted their permissions in some circumstances.
CVE-2026-53437 High 2026-06-10 No exploit published No public exploit Jenkins 2.567 and earlier, LTS 2.555.2 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins when it contains tab or newline characters between `//`, allowing attackers to perform phishing attacks.
CVE-2026-53435 High 2026-06-10 Protected by Waratek Exploited In Jenkins 2.567 and earlier, LTS 2.555.2 and earlier, it is possible for attackers to have Jenkins deserialize arbitrary types defined in Jenkins core or plugins from an attacker-controlled `config.xml` submission in a way that allows them to handle HTTP requests afterwards. This can be used to impersonate any user and send HTTP requests on their behalf, up to and including use of the Script Console to run arbitrary code, or to read arbitrary files from the Jenkins controller.
CVE-2026-33002 High 2026-03-18 No exploit published No public exploit Jenkins 2.442 through 2.554 (both inclusive), LTS 2.426.3 through LTS 2.541.2 (both inclusive) performs origin validation of requests made through the CLI WebSocket endpoint by computing the expected origin for comparison using the Host or X-Forwarded-Host HTTP request headers, making it vulnerable to DNS rebinding attacks that allow bypassing origin validation.
CVE-2026-33001 High 2026-03-18 Protected by Waratek No public exploit Jenkins 2.554 and earlier, LTS 2.541.2 and earlier does not safely handle symbolic links during the extraction of .tar and .tar.gz archives, allowing crafted archives to write files to arbitrary locations on the filesystem, restricted only by file system access permissions of the user running Jenkins. This can be exploited to deploy malicious scripts or plugins on the controller by attackers with Item/Configure permission, or able to control agent processes.
CVE-2026-27099 High 2026-02-18 No exploit published No public exploit Jenkins 2.483 through 2.550 (both inclusive), LTS 2.492.1 through 2.541.1 (both inclusive) does not escape the user-provided description of the "Mark temporarily offline" offline cause, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Agent/Configure or Agent/Disconnect permission.
CVE-2025-67635 High 2025-12-10 No exploit published No public exploit Jenkins 2.540 and earlier, LTS 2.528.2 and earlier does not properly close HTTP-based CLI connections when the connection stream becomes corrupted, allowing unauthenticated attackers to cause a denial of service.
CVE-2024-43044 High 2024-08-07 Protected by Waratek Proof of concept only Jenkins 2.470 and earlier, LTS 2.452.3 and earlier allows agent processes to read arbitrary files from the Jenkins controller file system by using the `ClassLoaderProxy#fetchJar` method in the Remoting library.
CVE-2024-23898 High 2024-01-24 No exploit published Forecast only Jenkins 2.217 through 2.441 (both inclusive), LTS 2.222.1 through 2.426.2 (both inclusive) does not perform origin validation of requests made through the CLI WebSocket endpoint, resulting in a cross-site WebSocket hijacking (CSWSH) vulnerability, allowing attackers to execute CLI commands on the Jenkins controller.
CVE-2023-44487 High 2023-10-10 Mitigation candidate Exploited The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2023-36478 High 2023-10-10 No exploit published No public exploit Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for HTTP/2 HPACK header values to exceed their size limit. `MetaDataBuilder.java` determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication by 4 in line 295 will overflow, and length will become negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered. Furthermore, `MetaDataBuilder.checkSize` allows for user-entered HPACK header value sizes to be negative, potentially leading to a very large buffer allocation later on when the user-entered size is multiplied by 2. This means that if a user provides a negative length value (or, more precisely, a length value which, when multiplied by the 4/3 fudge factor, is negative), and this length value is a very large positive number when multiplied by 2, then the user can cause a very large buffer to be allocated on the server. Users of HTTP/2 can be impacted by a remote denial of service attack. The issue has been fixed in versions 11.0.16, 10.0.16, and 9.4.53. There are no known workarounds.
CVE-2023-43498 High 2023-09-20 No exploit published No public exploit In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, processing file uploads using MultipartFormDataParser creates temporary files in the default system temporary directory with the default permissions for newly created files, potentially allowing attackers with access to the Jenkins controller file system to read and write the files before they are used.
CVE-2023-43497 High 2023-09-20 No exploit published No public exploit In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, processing file uploads using the Stapler web framework creates temporary files in the default system temporary directory with the default permissions for newly created files, potentially allowing attackers with access to the Jenkins controller file system to read and write the files before they are used.
CVE-2023-43496 High 2023-09-20 No exploit published No public exploit Jenkins 2.423 and earlier, LTS 2.414.1 and earlier creates a temporary file in the system temporary directory with the default permissions for newly created files when installing a plugin from a URL, potentially allowing attackers with access to the system temporary directory to replace the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.
CVE-2023-35141 High 2023-06-14 No exploit published No public exploit In Jenkins 2.399 and earlier, LTS 2.387.3 and earlier, POST requests are sent in order to load the list of context actions. If part of the URL includes insufficiently escaped user-provided values, a victim may be tricked into sending a POST request to an unexpected endpoint by opening a context menu.
CVE-2023-27901 High 2023-03-10 No exploit published No public exploit Jenkins 2.393 and earlier, LTS 2.375.3 and earlier uses the Apache Commons FileUpload library without specifying limits for the number of request parts introduced in version 1.5 for CVE-2023-24998 in org.kohsuke.stapler.RequestImpl, allowing attackers to trigger a denial of service.
CVE-2023-27900 High 2023-03-10 No exploit published No public exploit Jenkins 2.393 and earlier, LTS 2.375.3 and earlier uses the Apache Commons FileUpload library without specifying limits for the number of request parts introduced in version 1.5 for CVE-2023-24998 in hudson.util.MultipartFormDataParser, allowing attackers to trigger a denial of service.
CVE-2023-27899 High 2023-03-10 No exploit published No public exploit Jenkins 2.393 and earlier, LTS 2.375.3 and earlier creates a temporary file in the default temporary directory with the default permissions for newly created files when uploading a plugin for installation, potentially allowing attackers with access to the Jenkins controller file system to read and write the file before it is used, potentially resulting in arbitrary code execution.
CVE-2022-2048 High 2022-07-07 No exploit published No public exploit In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests.
CVE-2022-34175 High 2022-06-23 No exploit published No public exploit Jenkins 2.335 through 2.355 (both inclusive) allows attackers in some cases to bypass a protection mechanism, thereby directly accessing some view fragments containing sensitive information, bypassing any permission checks in the corresponding view.
CVE-2022-34174 High 2022-06-23 No exploit published No public exploit In Jenkins 2.355 and earlier, LTS 2.332.3 and earlier, an observable timing discrepancy on the login form allows distinguishing between login attempts with an invalid username, and login attempts with a valid username and wrong password, when using the Jenkins user database security realm.
CVE-2022-0538 High 2022-02-09 No exploit published No public exploit Jenkins 2.333 and earlier, LTS 2.319.2 and earlier defines custom XStream converters that have not been updated to apply the protections for the vulnerability CVE-2021-43859 and allow unconstrained resource usage.
CVE-2021-43859 High 2022-02-01 No exploit published Proof of concept only XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.
CVE-2021-21695 High 2021-11-04 No exploit published No public exploit FilePath#listFiles lists files outside directories that agents are allowed to access when following symbolic links in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
CVE-2021-21688 High 2021-11-04 No exploit published No public exploit The agent-to-controller security check FilePath#reading(FileVisitor) in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not reject any operations, allowing users to have unrestricted read access using certain operations (creating archives, FilePath#copyRecursiveTo).
CVE-2021-21686 High 2021-11-04 Protected by Waratek No public exploit File path filters in the agent-to-controller security subsystem of Jenkins 2.318 and earlier, LTS 2.303.2 and earlier do not canonicalize paths, allowing operations to follow symbolic links to outside allowed directories.
CVE-2021-21671 High 2021-06-30 No exploit published No public exploit Jenkins 2.299 and earlier, LTS 2.289.1 and earlier does not invalidate the previous session on login.
CVE-2021-28165 High 2021-04-01 No exploit published Forecast only In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can reach 100% upon receiving a large invalid TLS frame.
CVE-2021-21605 High 2021-01-13 Protected by Waratek No public exploit Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows users with Agent/Configure permission to choose agent names that cause Jenkins to override the global `config.xml` file.
CVE-2021-21604 High 2021-01-13 Protected by Waratek No public exploit Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows attackers with permission to create or configure various objects to inject crafted content into Old Data Monitor that results in the instantiation of potentially unsafe objects once discarded by an administrator.
CVE-2020-2160 High 2020-03-25 No exploit published No public exploit Jenkins 2.227 and earlier, LTS 2.204.5 and earlier uses different representations of request URL paths, which allows attackers to craft URLs that allow bypassing CSRF protection of any target URL.
CVE-2012-0785 High 2020-02-24 No exploit published No public exploit Hash collision attack vulnerability in Jenkins before 1.447, Jenkins LTS before 1.424.2, and Jenkins Enterprise by CloudBees 1.424.x before 1.424.2.1 and 1.400.x before 1.400.0.11 could allow remote attackers to cause a considerable CPU load, aka "the Hash DoS attack."
CVE-2020-2099 High 2020-01-29 No exploit published No public exploit Jenkins 2.213 and earlier, LTS 2.204.1 and earlier improperly reuses encryption key parameters in the Inbound TCP Agent Protocol/3, allowing unauthorized attackers with knowledge of agent names to obtain the connection secrets for those agents, which can be used to connect to Jenkins, impersonating those agents.
CVE-2015-1811 High 2020-01-15 Protected by Waratek No public exploit XML external entity (XXE) vulnerability in CloudBees Jenkins before 1.600 and LTS before 1.596.1 allows remote attackers to read arbitrary XML files via a crafted XML document.

CVE-2012-4438 High 2019-11-18 No exploit published No public exploit Jenkins main before 1.482 and LTS before 1.466.2 allows remote attackers with read access and HTTP access to Jenkins master to insert data and execute arbitrary code.
CVE-2019-10384 High 2019-08-28 No exploit published No public exploit Jenkins 2.191 and earlier, LTS 2.176.2 and earlier allowed users to obtain CSRF tokens without an associated web session ID, resulting in CSRF tokens that did not expire and could be used to bypass CSRF protection for the anonymous user.
CVE-2019-10353 High 2019-07-17 No exploit published No public exploit CSRF tokens in Jenkins 2.185 and earlier, LTS 2.176.1 and earlier did not expire, thereby allowing attackers able to obtain them to bypass CSRF protection.
CVE-2019-1003049 High 2019-04-10 No exploit published No public exploit Users who cached their CLI authentication before Jenkins was updated to 2.150.2 and newer, or 2.160 and newer, would remain authenticated in Jenkins 2.171 and earlier and Jenkins LTS 2.164.1 and earlier, because the fix for CVE-2019-1003004 in these releases did not reject existing remoting-based CLI authentication caches.
CVE-2019-1003004 High 2019-01-22 No exploit published No public exploit An improper authorization vulnerability exists in Jenkins 2.158 and earlier, LTS 2.150.1 and earlier in core/src/main/java/hudson/security/AuthenticationProcessingFilter2.java that allows attackers to extend the duration of active HTTP sessions indefinitely even though the user account may have been deleted in the mean time.
CVE-2019-1003003 High 2019-01-22 No exploit published No public exploit An improper authorization vulnerability exists in Jenkins 2.158 and earlier, LTS 2.150.1 and earlier in core/src/main/java/hudson/security/TokenBasedRememberMeServices2.java that allows attackers with Overall/RunScripts permission to craft Remember Me cookies that would never expire, allowing e.g. to persist access to temporarily compromised user accounts.
CVE-2018-1000410 High 2019-01-09 No exploit published No public exploit An information exposure vulnerability exists in Jenkins 2.145 and earlier, LTS 2.138.1 and earlier, and the Stapler framework used by these releases, in core/src/main/java/org/kohsuke/stapler/RequestImpl.java, core/src/main/java/hudson/model/Descriptor.java that allows attackers with Overall/Administer permission or access to the local file system to obtain credentials entered by users if the form submission could not be successfully processed.
CVE-2018-1000863 High 2018-12-10 Protected by Waratek No public exploit A data modification vulnerability exists in Jenkins 2.153 and earlier, LTS 2.138.3 and earlier in User.java, IdStrategy.java that allows attackers to submit crafted user names that can cause an improper migration of user record storage formats, potentially preventing the victim from logging into Jenkins.
CVE-2018-1999043 High 2018-08-23 No exploit published No public exploit A denial of service vulnerability exists in Jenkins 2.137 and earlier, 2.121.2 and earlier in BasicAuthenticationFilter.java, BasicHeaderApiTokenAuthenticator.java that allows attackers to create ephemeral in-memory user records by attempting to log in using invalid credentials.
CVE-2018-1999002 High 2018-07-23 Mitigation candidate Working exploit published A arbitrary file read vulnerability exists in Jenkins 2.132 and earlier, 2.121.1 and earlier in the Stapler web framework's org/kohsuke/stapler/Stapler.java that allows attackers to send crafted HTTP requests returning the contents of any file on the Jenkins master file system that the Jenkins master has access to.
CVE-2018-1999001 High 2018-07-23 No exploit published No public exploit A unauthorized modification of configuration vulnerability exists in Jenkins 2.132 and earlier, 2.121.1 and earlier in User.java that allows attackers to provide crafted login credentials that cause Jenkins to move the config.xml file from the Jenkins home directory. If Jenkins is started without this file present, it will revert to the legacy defaults of granting administrator access to anonymous users.
CVE-2018-1000194 High 2018-06-05 Protected by Waratek No public exploit A path traversal vulnerability exists in Jenkins 2.120 and older, LTS 2.107.2 and older in FilePath.java, SoloFilePathFilter.java that allows malicious agents to read and write arbitrary files on the Jenkins master, bypassing the agent-to-master security subsystem protection.
CVE-2017-2608 High 2018-05-15 No exploit published No public exploit Jenkins before versions 2.44, 2.32.2 is vulnerable to a remote code execution vulnerability involving the deserialization of various types in javax.imageio in XStream-based APIs (SECURITY-383).
CVE-2017-1000356 High 2018-01-29 No exploit published No public exploit Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an issue in the Jenkins user database authentication realm: create an account if signup is enabled; or create an account if the victim is an administrator, possibly deleting the existing default admin user in the process and allowing a wide variety of impacts.
CVE-2017-1000354 High 2018-01-29 No exploit published No public exploit Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to a login command which allowed impersonating any Jenkins user. The `login` command available in the remoting-based CLI stored the encrypted user name of the successfully authenticated user in a cache file used to authenticate further commands. Users with sufficient permission to create secrets in Jenkins, and download their encrypted values (e.g. with Job/Configure permission), were able to impersonate any other Jenkins user on the same instance.
CVE-2017-1000394 High 2018-01-26 No exploit published No public exploit Jenkins 2.73.1 and earlier, 2.83 and earlier bundled a version of the commons-fileupload library with the denial-of-service vulnerability known as CVE-2016-3092. The fix for that vulnerability has been backported to the version of the library bundled with Jenkins.
CVE-2017-1000393 High 2018-01-26 Protected by Waratek No public exploit Jenkins 2.73.1 and earlier, 2.83 and earlier users with permission to create or configure agents in Jenkins could configure a launch method called 'Launch agent via execution of command on master'. This allowed them to run arbitrary shell commands on the master node whenever the agent was supposed to be launched. Configuration of this launch method now requires the Run Scripts permission typically only granted to administrators.
CVE-2017-1000391 High 2018-01-26 No exploit published No public exploit Jenkins versions 2.88 and earlier and 2.73.2 and earlier stores metadata related to 'people', which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping, potentially resulting in problems like overwriting of unrelated configuration files.
CVE-2017-1000504 High 2018-01-24 No exploit published No public exploit A race condition during Jenkins 2.94 and earlier; 2.89.1 and earlier startup could result in the wrong order of execution of commands during initialization. There is a very short window of time after startup during which Jenkins may no longer show the 'Please wait while Jenkins is getting ready to work' message but Cross-Site Request Forgery (CSRF) protection may not yet be effective.
CVE-2017-1000503 High 2018-01-24 No exploit published No public exploit A race condition during Jenkins 2.81 through 2.94 (inclusive); 2.89.1 startup could result in the wrong order of execution of commands during initialization. This could in rare cases result in failure to initialize the setup wizard on the first startup. This resulted in multiple security-related settings not being set to their usual strict default.
