Name of the Vulnerable Software and Affected Versions MediaWiki versions prior to 1.35.6 MediaWiki versions 1.36.x prior to 1.36.4 MediaWiki versions 1.37.x prior to 1.37.2

Description A denial-of-service issue was discovered in MediaWiki. When many files exist, requesting Special:NewFiles with actor as a condition can result in a very long running query.

Recommendations For MediaWiki versions prior to 1.35.6, update to version 1.35.6 or later. For MediaWiki versions 1.36.x prior to 1.36.4, update to version 1.36.4 or later. For MediaWiki versions 1.37.x prior to 1.37.2, update to version 1.37.2 or later. As a temporary workaround, consider restricting access to the Special:NewFiles page with the actor condition until a patch is available.
