No CVSS score has been assigned to GHSA-9gp7-6833-wv89 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-9gp7-6833-wv89?

GHSA-9gp7-6833-wv89 affects the following packages: go.etcd.io/etcd/client/v3 (Go), go.etcd.io/etcd/client/v3 (Go). Ecosystems affected: Go.

How do I fix GHSA-9gp7-6833-wv89?

Update go.etcd.io/etcd/client/v3 to 3.4.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9gp7-6833-wv89 is resolved across your whole dependency graph.

How do I detect GHSA-9gp7-6833-wv89 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for go.etcd.io/etcd/client/v3. 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-9gp7-6833-wv89 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-9gp7-6833-wv89?

O3 pinpoints whether GHSA-9gp7-6833-wv89 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-9gp7-6833-wv89 actively exploited in the wild?

No public exploit code has been indexed for GHSA-9gp7-6833-wv89 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.

When was GHSA-9gp7-6833-wv89 published, and has it been updated?

GHSA-9gp7-6833-wv89 was published on October 6, 2022. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
