Description
Hello Kubernetes Community,
A security issue was discovered in secrets-store-sync-controller where an actor with access to the controller logs could observe service account tokens. These tokens could then potentially be exchanged with external cloud providers to access secrets stored in cloud vault solutions. Tokens are only logged when there is a specific error marshaling the parameters sent to the providers.
Am I vulnerable?
To check if tokens are being logged, examine the manager container log:
kubectl logs -l 'app.kubernetes.io/part-of=secrets-store-sync-controller' -c manager -f | grep --line-buffered "csi.storage.k8s.io/serviceAccount.tokens"
Affected Versions
- secrets-store-sync-controller < v0.0.2
How do I mitigate this vulnerability?
Upgrade to secrets-store-sync-controller v0.0.2+
Fixed Versions
- secrets-store-sync-controller >= v0.0.2
Detection
Examine cloud provider logs for unexpected token exchanges, as well as unexpected access to cloud vault secrets.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sigs.k8s.io/secrets-store-sync-controller. 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.
Fix
Update sigs.k8s.io/secrets-store-sync-controller to 0.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rcw7-pqfp-735x is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-rcw7-pqfp-735x 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-rcw7-pqfp-735x. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-rcw7-pqfp-735x in your dependencies?
O3 detects GHSA-rcw7-pqfp-735x across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
