Uncontrolled Resource Consumption vulnerability in the examples web application provided with Apache Tomcat leads to denial of service. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.9.97. 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 11.0.2, 10.1.34 or 9.0.98, which fixes the issue. This vulnerability does not affect core Apache Tomcat server components (tomcat-catalina, tomcat-coyote, tomcat-embed-core, etc.). Removing the `webapps/examples/` directory in production environments — as recommended by the [Apache Tomcat Security Considerations documentation](https://tomcat.apache.org/tomcat-9.0-doc/security-howto.html#Examples) — eliminates the attack surface entirely.

Update org.apache.tomcat:tomcat to 11.0.2; org.apache.tomcat:tomcat to 10.1.34; org.apache.tomcat:tomcat to 9.0.98 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in maven. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
