Name of the Vulnerable Software and Affected Versions MediaWiki versions 1.31.12 and earlier MediaWiki versions 1.32.x through 1.35.1

Description An issue in MediaWiki 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. The problem is related to shortcomings in the authentication procedure, which could allow an attacker to disclose protected information.

Recommendations For MediaWiki versions 1.31.12 and earlier, update to version 1.31.12 or later. For MediaWiki versions 1.32.x through 1.35.1, update to version 1.35.2 or later. As a temporary workaround, consider restricting access to the Special:ResetTokens page for blocked users until a patch is available.
