Multiple security issues were found in MediaWiki, a website engine for collaborative work, which could result in incomplete page/blocking protection, denial of service or cross-site scripting.
For the stable distribution (buster), these problems have been fixed in version 1:1.31.14-1~deb10u1.
We recommend that you upgrade your mediawiki packages.
