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

How do I mitigate GHSA-3gm8-32vv-q8mp if there is no patch (or I can't update yet)?

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.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

The KSES text cleaning filter in lib/weblib.php in Moodle before 1.8.13 and 1.9.x before 1.9.9 does not properly handle vbscript URIs, which allows remote authenticated users to conduct cross-site scripting (XSS) attacks via HTML input.
