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).
