    This release includes bug fixes, enhancements and component upgrades, which are documented in the Release
    Notes that are linked to in the References section.

    Security Fix(es):

    * tomcat-catalina: Apache Tomcat: Misleading security logs due to incorrect control flow (CVE-2026-55276)
    * tomcat-coyote-ffm: Apache Tomcat: Error condition not handled when configuring CRL (CVE-2026-53434)
    * jws6-tomcat: Apache Tomcat: Security constraint bypass via improper URL encoding in rewrite valve
    (CVE-2026-59083)
    * tomcat: Apache Tomcat: Local information disclosure via Unix domain socket TOCTOU race condition
    (CVE-2026-65183)
    * tomcat: Apache Tomcat: Security constraint bypass due to improper access control (CVE-2026-65182)
    * tomcat: Apache Tomcat: Access control bypass due to off-by-one error in RewriteValve [N] flag processing

    * tomcat: Apache Tomcat - DoS in WebSocket chat example (CVE-2026-66299)
    * tomcat: Apache Tomcat: Authenticated WebSocket session persists after HTTP session termination
    (CVE-2026-73180)
    * tomcat: Apache Tomcat: Improper Authorization allows bypass of declarative role constraints
    (CVE-2026-66422)
    * tomcat: Apache Tomcat: Improper Authentication due to principal lookup failure (CVE-2026-68569)
    * tomcat: Apache Tomcat: Authentication bypass via limited replay attack in DIGEST authenticator
    (CVE-2026-65905)
