    Several vulnerabilities have been discovered in the WebKitGTK web     engine, that may lead to heap corruption, local privilege escalation,     remote code execution, out-of-bounds memory access, cross-origin data     leak and sandbox escape, among other problems.

    See the WebKitGTK security advisory for details on each vulnerability:
    https://webkitgtk.org/security/WSA-2026-0006.html

    For the stable distribution (trixie), these problems have been fixed in     version 2.54.0-1~deb13u1.

    We recommend that you upgrade your webkit2gtk packages.

    For the detailed security status of webkit2gtk please refer to     its security tracker page at:
