    CVE ID         : CVE-2025-3469 CVE-2025-32696 CVE-2025-32697

    Multiple security issues were discovered in MediaWiki, a website engine
    for collaborative work, which could result in information disclosure,
    cross-site scripting or restriction bypass.

    For the stable distribution (bookworm), these problems have been fixed in
    version 1:1.39.12-1~deb12u1.

    We recommend that you upgrade your mediawiki packages.

    For the detailed security status of mediawiki please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/mediawiki
