How do I fix GHSA-c7w6-33j3-j3mx?

No patched version of ryu has shipped for GHSA-c7w6-33j3-j3mx yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

How do I detect GHSA-c7w6-33j3-j3mx in my PyPI dependencies?

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

How do I mitigate GHSA-c7w6-33j3-j3mx 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-c7w6-33j3-j3mx?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-c7w6-33j3-j3mx can be triaged on real exposure rather than presence alone.

Is GHSA-c7w6-33j3-j3mx actively exploited in the wild?

No public exploit code has been indexed for GHSA-c7w6-33j3-j3mx 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-c7w6-33j3-j3mx?

GHSA-c7w6-33j3-j3mx has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 39th 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.

What type of vulnerability is GHSA-c7w6-33j3-j3mx?
