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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for go.etcd.io/etcd/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.

  2. Fix

    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.

  3. Workarounds

    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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-vjg6-93fv-qv64 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-vjg6-93fv-qv64. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
