Security Fix(es): Improper Handling of Case Sensitivity vulnerability in Apache Tomcat_x27;s GCI servlet allows security constraint bypass of security constraints that apply to the pathInfo component of a URI mapped to the CGI servlet. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.6, from 10.1.0-M1 through 10.1.40, from 9.0.0.M1 through 9.0.104. Users are recommended to upgrade to version 11.0.7, 10.1.41 or 9.0.105, which fixes the issue. (CVE-2025-46701) 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-M1 through 11.0.5, from 10.1.0-M1 through 10.1.39, from 9.0.0.M1 through 9.0.102. Users are recommended to upgrade to version [FIXED_VERSION], which fixes the issue. (CVE-2025-31651) 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.
