Security readout for executives and security teams

An old MediaWiki XSS flaw lets a remote attacker inject script or HTML through crafted CSS comments. For a business, the concern is user trust and session risk on public or internal wikis, especially where privileged users view attacker-controlled content. The source bundle identifies MediaWiki before 1.16.2 as affected. Exposure is most likely on legacy MediaWiki installations older than 1.16.2, including distribution-packaged deployments that were not updated after the 2011 security release. Treat as a legacy hygiene issue unless an exposed outdated MediaWiki instance is found. If present on a public wiki, prioritize remediation because XSS can affect authenticated users and administrators. Mitigation focus: Upgrade MediaWiki to 1.16.2 or a supported later release.; Apply relevant distribution updates, including Fedora packages where applicable.; Retire or isolate unsupported legacy MediaWiki instances..
