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

How do I mitigate GHSA-mq3p-rrmp-79jg 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-mq3p-rrmp-79jg?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-mq3p-rrmp-79jg can be triaged on real exposure rather than presence alone.

Is GHSA-mq3p-rrmp-79jg actively exploited in the wild?

No public exploit code has been indexed for GHSA-mq3p-rrmp-79jg yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-mq3p-rrmp-79jg?

GHSA-mq3p-rrmp-79jg has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 49th 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.
