GHSA-xv9f-728h-9jgv has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by GHSA-xv9f-728h-9jgv?

GHSA-xv9f-728h-9jgv affects the following packages: github.com/chaos-mesh/chaos-mesh (Go). Ecosystems affected: Go.

How do I fix GHSA-xv9f-728h-9jgv?

Update github.com/chaos-mesh/chaos-mesh to 2.7.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xv9f-728h-9jgv is resolved across your whole dependency graph.

How do I detect GHSA-xv9f-728h-9jgv in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/chaos-mesh/chaos-mesh. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-xv9f-728h-9jgv 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-xv9f-728h-9jgv?

O3 pinpoints whether GHSA-xv9f-728h-9jgv is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-xv9f-728h-9jgv actively exploited in the wild?

No public exploit code has been indexed for GHSA-xv9f-728h-9jgv 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-xv9f-728h-9jgv?

GHSA-xv9f-728h-9jgv has an EPSS (Exploit Prediction Scoring System) score of 2.8%, placing it in the 85th 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.

When was GHSA-xv9f-728h-9jgv published, and has it been updated?

GHSA-xv9f-728h-9jgv was published on September 15, 2025 and was last updated on September 17, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
