How do I fix GHSA-c4p9-87h3-7vr4?

Update keystone to 8.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c4p9-87h3-7vr4 is resolved across your whole dependency graph.

How do I detect GHSA-c4p9-87h3-7vr4 in my PyPI dependencies?

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

How do I mitigate GHSA-c4p9-87h3-7vr4 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-c4p9-87h3-7vr4?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-c4p9-87h3-7vr4 can be triaged on real exposure rather than presence alone.

Is GHSA-c4p9-87h3-7vr4 actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-c4p9-87h3-7vr4, 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-c4p9-87h3-7vr4?

GHSA-c4p9-87h3-7vr4 has an EPSS (Exploit Prediction Scoring System) score of 1.4%, placing it in the 71th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.
