    Multiple security issues were discovered in MediaWiki, a website engine
    for collaborative work, which could result in information disclosure,
    code execution via unsafe deserialisation or cross-site scripting.

    For the stable distribution (trixie), these problems have been fixed in
    version 1:1.43.9+dfsg-1~deb13u1.

    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

    these updates to your system and frequently asked questions can be
