Cross-site scripting (XSS) vulnerability in includes/actions/InfoAction.php in MediaWiki before 1.21.9 and 1.22.x before 1.22.6 allows remote attackers to inject arbitrary web script or HTML via the sort key in an info action.

Security readout for executives and security teams

CVE-2014-2853 is a MediaWiki cross-site scripting issue. A remote attacker could inject script or HTML through the info action sort key in vulnerable versions. For a business, the main concern is browser-side account abuse, especially if administrators or editors visit affected pages. Exposure is likely limited to organizations still running MediaWiki before 1.21.9 or 1.22.x before 1.22.6. Publicly reachable wikis and authenticated editorial workflows matter most because XSS impact depends on who views the crafted content. Treat this as a routine but real web-application security update. It is not KEV-listed in the provided data, but unpatched public MediaWiki sites can expose privileged users to browser-side compromise. Mitigation focus: Upgrade MediaWiki 1.21 deployments to 1.21.9 or later.; Upgrade MediaWiki 1.22 deployments to 1.22.6 or later.; Check Wikimedia release notes and vendor/package guidance for supported upgrade paths..
