Publication date: 12 Jul 2021
URL: https://advisories.mageia.org/MGASA-2021-0346.html
Type: security
Affected Mageia releases: 7, 8
CVE: CVE-2021-35197

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.
