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

How do I mitigate GHSA-579v-mp3v-rrw5 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.

Is GHSA-579v-mp3v-rrw5 actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-579v-mp3v-rrw5, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-579v-mp3v-rrw5?

GHSA-579v-mp3v-rrw5 has an EPSS (Exploit Prediction Scoring System) score of 19.2%, placing it in the 97th percentile of all CVEs.
