MediaWiki 1.2x before 1.22.15, 1.23.x before 1.23.8, and 1.24.x before 1.24.1 allows remote attackers to bypass CORS restrictions in $wgCrossSiteAJAXdomains via a domain that has a partial match to an allowed origin, as demonstrated by "http://en.wikipedia.org.evilsite.example/."

Security readout for executives and security teams

This issue lets a remote website bypass MediaWiki’s intended cross-origin restrictions when the allowed-domain check matches only part of a domain name. The business risk is unauthorized browser-mediated access where the wiki deliberately allowed cross-site AJAX for trusted origins. Exposure is likely limited to legacy MediaWiki deployments using affected versions and configured cross-site AJAX domain allowances. Internet-facing wikis with sensitive authenticated content are higher concern. Treat as a targeted legacy-platform risk, not an emergency absent evidence of exploitation. Prioritize remediation for exposed MediaWiki sites containing non-public or business-sensitive information. Mitigation focus: Upgrade MediaWiki to 1.22.15, 1.23.8, 1.24.1, or a newer supported release.; Review $wgCrossSiteAJAXdomains for unnecessary or overly broad trusted origins.; Check Wikimedia and distribution advisories for branch-specific maintenance guidance..
