MediaWiki before 1.19.6 and 1.20.x before 1.20.5 allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated by a CDATA section containing valid UTF-7 encoded sequences in a SVG file, which is then incorrectly interpreted as UTF-8 by Chrome and Firefox.

Security readout for executives and security teams

Older MediaWiki releases mishandled certain SVG content, allowing a remote attacker to trigger cross-site scripting in users' browsers. The business risk is abuse of trusted wiki pages to run unauthorized browser-side actions against visitors, especially logged-in users. The bundle identifies fixed releases but does not show active exploitation. Likely exposure is legacy MediaWiki deployments below 1.19.6 or 1.20.5, especially public wikis that allow SVG upload or serve user-controlled SVG content. The bundle's affected product metadata is incomplete, so confirm exposure from installed MediaWiki version and configuration. Prioritize remediation for internet-facing or internally trusted MediaWiki sites with authenticated users. This is not supported as actively exploited in the provided sources, but XSS in a trusted collaboration platform can create meaningful account and data-access risk. Mitigation focus: Upgrade MediaWiki to 1.19.6, 1.20.5, or a later supported release.; Review Wikimedia, Debian, Fedora, or Gentoo advisories for package-specific update guidance.; Restrict untrusted SVG upload or serving until vulnerable instances are upgraded..
