Cross-site request forgery (CSRF) vulnerability in the CentralAuth extension for MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 allows remote attackers to hijack the authentication of users for requests that login via vectors involving image loading.

Security readout for executives and security teams

This is an old MediaWiki CentralAuth flaw where a malicious site could abuse a logged-in user's browser to interfere with login-related authentication requests. It matters mainly for organizations still running unpatched MediaWiki/CentralAuth releases. The sources do not provide CVSS scoring or evidence of active exploitation. Exposure is likely limited to MediaWiki deployments using the CentralAuth extension on versions older than 1.19.9, 1.20.8, or 1.21.3. Systems not using CentralAuth, or already updated past those releases, are not indicated as affected by the provided sources. Treat as moderate priority unless legacy MediaWiki remains in production. The main business risk is outdated shared-authentication infrastructure. Confirm inventory first, then patch or retire affected systems. Mitigation focus: Upgrade MediaWiki/CentralAuth to 1.19.9, 1.20.8, 1.21.3, or later supported releases.; Review Wikimedia and downstream OS vendor advisories for package-specific update guidance.; Prioritize internet-facing or shared-authentication wiki deployments..
