The User::matchEditToken function in includes/User.php in MediaWiki before 1.23.12, 1.24.x before 1.24.5, 1.25.x before 1.25.4, and 1.26.x before 1.26.1 does not perform token comparison in constant time before determining if a debugging message should be logged, which allows remote attackers to guess the edit token and bypass CSRF protection via a timing attack, a different vulnerability than CVE-2015-8623.

Security readout for executives and security teams

Older MediaWiki releases compared edit tokens in a way that could leak timing information. A remote attacker could use that weakness to guess a valid edit token and bypass CSRF protection. The issue was fixed in December 2015 security releases. Exposure is limited to MediaWiki deployments running the listed pre-fix versions, especially public or internet-reachable wikis. The bundle does not identify affected downstream distributions or hosted services. Prioritize remediation for any internet-facing or business-critical MediaWiki instance still on the affected branches. This is an old issue with clear fixed versions, but legacy systems may remain exposed. Mitigation focus: Upgrade MediaWiki to 1.23.12, 1.24.5, 1.25.4, 1.26.1, or later supported releases.; Check Wikimedia security guidance for branch-specific backports or upgrade constraints.; Retire unsupported MediaWiki versions where feasible..
