Security readout for executives and security teams
This is a cross-site scripting issue in MediaWiki sites using the ZeroRatedMobileAccess extension. A remote attacker could inject browser-executed script or HTML through the index.php "to" parameter on affected 1.19, 1.20, and 1.21 releases. No active exploitation evidence is provided in the source bundle. Exposure is likely limited to MediaWiki deployments running the ZeroRatedMobileAccess extension on the affected release branches before the named security releases. Organizations not using that extension, or already on fixed versions, are unlikely to be affected based on the provided sources. Treat as a moderate legacy web risk. Prioritize any internet-facing MediaWiki instance still running the affected extension and old branches, especially where administrator sessions or trusted users may browse the site. Mitigation focus: Upgrade affected MediaWiki branches to 1.19.9, 1.20.8, 1.21.3, or later supported guidance.; Confirm whether ZeroRatedMobileAccess is installed and enabled on public MediaWiki sites.; Review the Wikimedia security release advisory for deployment-specific instructions..
