Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

Security Fix(es):

* tomcat: Apache Tomcat: Bypass of rules in Rewrite Valve (CVE-2025-31651) * tomcat: org.apache.tomcat/tomcat-catalina: Apache Tomcat: Directory traversal via rewrite with possible RCE (CVE-2025-55752)

Affected: Bitnami: tomcat

Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. For a subset of unlikely rewrite rule configurations, it was possible for a specially crafted request to bypass some rewrite rules. If those rewrite rules effectively enforced security constraints, those constraints could be bypassed.

This issue affects Apache Tomcat: from 11.0.0 through 11.0.5, from 10.1.0 through 10.1.39, from 9.0.0 through 9.0.102. 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 [FIXED_VERSION], which fixes the issue.

Affected: CleanStart: tomcat10

Security vulnerability affects the tomcat10 package. This issue is resolved in later releases. See references for vulnerability details.

Tomcat is the servlet container that is used in the official Reference Implementation for the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process. Security Fix(es):

Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A large number of such requests could trigger an OutOfMemoryException resulting in a denial of service.

This issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2 through 11.0.5.

Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the issue.(CVE-2025-31650)
