How severe is GHSA-vjg6-93fv-qv64?

No CVSS score has been assigned to GHSA-vjg6-93fv-qv64 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-vjg6-93fv-qv64?

GHSA-vjg6-93fv-qv64 affects the following packages: go.etcd.io/etcd/v3 (Go), go.etcd.io/etcd/v3 (Go). Ecosystems affected: Go.

How do I fix GHSA-vjg6-93fv-qv64?

Update go.etcd.io/etcd/v3 to 3.4.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vjg6-93fv-qv64 is resolved across your whole dependency graph.

How do I detect GHSA-vjg6-93fv-qv64 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for go.etcd.io/etcd/v3, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-vjg6-93fv-qv64 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-vjg6-93fv-qv64?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-vjg6-93fv-qv64 can be triaged on real exposure rather than presence alone.

Is GHSA-vjg6-93fv-qv64 actively exploited in the wild?

No public exploit code has been indexed for GHSA-vjg6-93fv-qv64 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.

Description

Vulnerability type

Logging

Detail

etcd users who have no password can authenticate only through a client certificate. When such users try to authenticate into etcd using the Authenticate endpoint, errors are logged with insufficient information regarding why the authentication failed, and may be misleading when auditing etcd logs.
