An issue was discovered in the AbuseFilter extension in MediaWiki through 1.36. If the MediaWiki:Abusefilter-blocker message is invalid within the content language, the filter user falls back to the English version, but that English version could also be invalid on a wiki. This would result in a fatal error, and potentially fail to block or restrict a potentially nefarious user.
CVE-2021-36127 1 Mediawiki 1 Mediawiki 2021-07-07 4.0 MEDIUM 4.3 MEDIUM
An issue was discovered in the CentralAuth extension in MediaWiki through 1.36.

An XSS issue was discovered in the SocialProfile extension in MediaWiki through 1.36.
