| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2026-55956 | Medium | 2026-06-29 | No exploit published | No public exploit | Improper Authorization vulnerability in Apache Tomcat leads to security constraints specified for the default servlet ignoring any method or method omission configured as part of the constraint. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.22, from 10.1.0-M1 through 10.1.55, from 9.0.0.M1 through 9.0.118, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other versions that have reached end of support may also be affected. Users are recommended to upgrade to version 11.0.23, 10.1.56 or 9.0.119, which fix the issue. |
| CVE-2026-32990 | Medium | 2026-04-09 | No exploit published | No public exploit | Improper Input Validation vulnerability in Apache Tomcat due to an incomplete fix of CVE-2025-66614. This issue affects Apache Tomcat: from 11.0.15 through 11.0.19, from 10.1.50 through 10.1.52, from 9.0.113 through 9.0.115. Users are recommended to upgrade to version 11.0.20, 10.1.53 or 9.0.116, which fix the issue. |
| CVE-2026-25854 | Medium | 2026-04-09 | No exploit published | No public exploit | Occasional URL redirection to untrusted Site ('Open Redirect') vulnerability in Apache Tomcat via the LoadBalancerDrainingValve. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.18, from 10.1.0-M1 through 10.1.52, from 9.0.0.M23 through 9.0.115, from 8.5.30 through 8.5.100. Other, unsupported versions may also be affected Users are recommended to upgrade to version 11.0.20, 10.1.53 or 9.0.116, which fix the issue. |
| CVE-2025-61795 | Medium | 2025-10-27 | No exploit published | No public exploit | Improper Resource Shutdown or Release vulnerability in Apache Tomcat. If an error occurred (including exceeding limits) during the processing of a multipart upload, temporary copies of the uploaded parts written to disc were not cleaned up immediately but left for the garbage collection process to delete. Depending on JVM settings, application memory usage and application load, it was possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1 through 9.0.109. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue. |
| CVE-2025-55668 | Medium | 2025-08-13 | Protected by Waratek | No public exploit | Session Fixation vulnerability in Apache Tomcat via rewrite valve. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.7, from 10.1.0-M1 through 10.1.41, from 9.0.0.M1 through 9.0.105. Older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.8, 10.1.42 or 9.0.106, which fix the issue. |
| CVE-2024-52317 | Medium | 2024-11-18 | No exploit published | No public exploit | Incorrect object re-cycling and re-use vulnerability in Apache Tomcat. Incorrect recycling of the request and response used by HTTP/2 requests could lead to request and/or response mix-up between users. This issue affects Apache Tomcat: from 11.0.0-M23 through 11.0.0-M26, from 10.1.27 through 10.1.30, from 9.0.92 through 9.0.95. Users are recommended to upgrade to version 11.0.0, 10.1.31 or 9.0.96, which fixes the issue. |
| CVE-2024-21733 | Medium | 2024-01-19 | Mitigation candidate | Proof of concept only | Generation of Error Message Containing Sensitive Information vulnerability in Apache Tomcat.This issue affects Apache Tomcat: from 8.5.7 through 8.5.63, from 9.0.0-M11 through 9.0.43. Other, EOL versions may also be affected. Users are recommended to upgrade to version 8.5.64 onwards or 9.0.44 onwards, which contain a fix for the issue. |
| CVE-2023-45648 | Medium | 2023-10-10 | Mitigation candidate | Working exploit published | Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue. |
| CVE-2023-42795 | Medium | 2023-10-10 | No exploit published | No public exploit | Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from 8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next. Older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue. |
| CVE-2023-41080 | Medium | 2023-08-25 | Mitigation candidate | Proof of concept only | URL Redirection to Untrusted Site ('Open Redirect') vulnerability in FORM authentication feature Apache Tomcat.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through 10.0.12, from 9.0.0-M1 through 9.0.79 and from 8.5.0 through 8.5.92. Older, EOL versions may also be affected. The vulnerability is limited to the ROOT (default) web application. |
| CVE-2021-24122 | Medium | 2021-01-14 | No exploit published | No public exploit | When serving resources from a network location using the NTFS file system, Apache Tomcat versions 10.0.0-M1 to 10.0.0-M9, 9.0.0.M1 to 9.0.39, 8.5.0 to 8.5.59 and 7.0.0 to 7.0.106 were susceptible to JSP source code disclosure in some configurations. The root cause was the unexpected behaviour of the JRE API File.getCanonicalPath() which in turn was caused by the inconsistent behaviour of the Windows API (FindFirstFileW) in some circumstances. |
| CVE-2020-1935 | Medium | 2020-02-24 | No exploit published | No public exploit | In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely. |
| CVE-2019-0221 | Medium | 2019-05-28 | Mitigation candidate | Working exploit published | The SSI printenv command in Apache Tomcat 9.0.0.M1 to 9.0.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 echoes user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv command is intended for debugging and is unlikely to be present in a production website. |
| CVE-2018-8037 | Medium | 2018-08-02 | No exploit published | No public exploit | If an async request was completed by the application at the same time as the container triggered the async timeout, a race condition existed that could result in a user seeing a response intended for a different user. An additional issue was present in the NIO and NIO2 connectors that did not correctly track the closure of the connection when an async request was completed by the application and timed out by the container at the same time. This could also result in a user seeing a response intended for another user. Versions Affected: Apache Tomcat 9.0.0.M9 to 9.0.9 and 8.5.5 to 8.5.31. |
| CVE-2014-0095 | Medium | 2014-05-31 | No exploit published | No public exploit | java/org/apache/coyote/ajp/AbstractAjpProcessor.java in Apache Tomcat 8.x before 8.0.4 allows remote attackers to cause a denial of service (thread consumption) by using a "Content-Length: 0" AJP request to trigger a hang in request processing. |
| CVE-2008-1947 | Medium | 2008-06-04 | No exploit published | No public exploit | Cross-site scripting (XSS) vulnerability in Apache Tomcat 5.5.9 through 5.5.26 and 6.0.0 through 6.0.16 allows remote attackers to inject arbitrary web script or HTML via the name parameter (aka the hostname attribute) to host-manager/html/add. |
