Debian: DSA-5957-1 mediawiki critical: XSS and info disclosure issues

Multiple security issues were discovered in MediaWiki, a website engine
for collaborative work, which could result in cross-site scripting,
information disclosure, HTML injection or incorrect tracking of
authentication events.

For the stable distribution (bookworm), these problems have been fixed in
version 1:1.39.13-1~deb12u1.

We recommend that you upgrade your mediawiki packages.

For the detailed security status of mediawiki please refer to
