CVE-2025-62159Network attack vector

Cross-namespace secret disclosure via unchecked namespace references

Published Oct 10, 2025 · Updated Oct 14, 2025

Improper access control in External Secrets Operator 0.10.1 through 0.19.2 allows attackers to read cross-namespace Kubernetes Secrets. The BeyondTrust provider directly dereferences namespace-qualified Kubernetes Secret keys without validating the store kind or namespace boundary. Reachability requires control of a BeyondTrust provider configuration that references another namespace, and exposure is limited to Secrets readable by the controller.
