CVE-2021-36126 1 Mediawiki 1 Mediawiki 2021-07-07 7.5 HIGH 9.8 CRITICAL
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-2021-36129 1 Mediawiki 1 Mediawiki 2021-07-07 4.0 MEDIUM 4.3 MEDIUM
An issue was discovered in the Translate extension in MediaWiki through 1.36. The Aggregategroups Action API module does not validate the parameter for aggregategroup when action=remove is set, thus allowing users with the translate-manage right to silently delete various groups' metadata.
