CVE-2021-30159 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. Users can bypass intended restrictions on deleting pages in certain "fast double move" situations. MovePage::isValidMoveTarget() uses FOR UPDATE, but it's only called if Title::getArticleID() returns non-zero with no special flags. Next, MovePage::moveToInternal() will delete the page if getArticleID(READ_LATEST) is non-zero. Therefore, if the page is missing in the replica DB, isValidMove() will return true, and then moveToInternal() will unconditionally delete the page if it can be found in the master.
CVE-2021-30158 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. Blocked users are unable to use Special:ResetTokens. This has security relevance because a blocked user might have accidentally shared a token, or might know that a token has been compromised, and yet is not able to block any potential future use of the token by an unauthorized party.

This is related to ApiVisualEditor.

An issue was discovered in the CasAuth extension for MediaWiki through 1.35.1.
