Dist Mageia Esm H88
Enhancements for MediaWiki address unauthorized bot access through APIs, bolstering security for Mageia users.
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

Summary

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) (CVE-2021-35197).
The mediawiki packages are upgraded to latest version for their branches. See upstream release notes for other bugfixes.
