CVE-2026-92414: Apache Jackrabbit: Pre-auth hijack of cached sessions via derivable WebDAV lock tokens

Apache Jackrabbit contains a session fixation vulnerability in its WebDAV server that allows attackers to reuse cached authenticated sessions via derivable lock tokens without authentication. The issue affects versions 2.20.0 through 2.20.17, 2.22.0 through 2.22.4, and 2.23.0 through 2.23.5, with a CVSS score of 9.3 (critical).

Why it matters: Organizations running affected Jackrabbit versions face immediate risk of unauthorized session hijacking and data access; patching or upgrading to fixed versions is required today.
