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.
