Description OSIDB Bzimport 2026-10-22 19:36:54 UTC 
OpenBao before 2.6.4 and 2.7.x before 2.7.1 does not verify, when renewing a token issued by the Kubernetes Auth method, that the service account token originally used to authenticate is still valid. An authenticated attacker can keep renewing such tokens to persist access after the Kubernetes service account has been deleted.
