How do I fix GHSA-gjx6-58xh-p7pw?

Update bolt/bolt to 3.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gjx6-58xh-p7pw is resolved across your whole dependency graph.

How do I detect GHSA-gjx6-58xh-p7pw in my Packagist dependencies?

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

How do I mitigate GHSA-gjx6-58xh-p7pw 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-gjx6-58xh-p7pw actively exploited in the wild?

Yes. There are 3 known exploit references for GHSA-gjx6-58xh-p7pw, including 1 documented proof-of-concept exploit on Exploit-DB and 2 in-the-wild exploitations 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-gjx6-58xh-p7pw?

GHSA-gjx6-58xh-p7pw has an EPSS (Exploit Prediction Scoring System) score of 3.5%, placing it in the 89th percentile of all CVEs.
