Debian DSA-5901-1: addressing security vulnerabilities in mediawiki

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:
