NVD Description

Note: Versions mentioned in the description apply only to the upstream mediawiki package and not the mediawiki package as distributed by Debian.

An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. On ChangesList special pages such as Special:RecentChanges and Special:Watchlist, some of the rcfilters-filter-* label messages are output in HTML unescaped, leading to XSS.
