Description

An issue was discovered in the Cargo extension in MediaWiki before 1.35.14, 1.36.x through 1.39.x before 1.39.6, and 1.40.x before 1.40.2. The Special:Drilldown page allows XSS via artist, album, and position parameters because of applied filter values in drilldown/CargoAppliedFilter.php.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mediawiki/cargo, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update mediawiki/cargo to 1.35.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rhpm-63w5-79rg is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
