Description

In MediaWiki before 1.31.15, 1.32.x through 1.35.x before 1.35.3, and 1.36.x before 1.36.1, bots have certain unintended API access. When a bot account has a "sitewide block" applied, it is able to still "purge" pages through the MediaWiki Action API (which a "sitewide block" should have prevented).

Affected configurations

• mediawiki mediawiki (< 1.31.15) • mediawiki mediawiki (>= 1.32.0 < 1.35.3) • mediawiki mediawiki (>= 1.36.0 < 1.36.1) • debian debian linux 9.0 • debian debian linux 10.0 • debian debian linux 11.0 • fedoraproject fedora 33 • fedoraproject fedora 34 • fedoraproject fedora 35
