CVE-2026-43515
Multiple security vulnerabilities have been discovered in Tomcat 11, a Java
based web server, servlet and JSP engine which may result in a denial of
service, authentication bypass or the disclosure of sensitive information.
Although we are not aware of any problems, new upstream versions may introduce
new options, limits or code changes which may or may not affect your existing
web applications. We recommend to consult the Tomcat 11 documentation for
further information.
For the stable distribution (trixie), these problems have been fixed in
version 11.0.22-1~deb13u1.
We recommend that you upgrade your tomcat11 packages.
For the detailed security status of tomcat11 please refer to
