Critical RCE Alert: Full takeover of HashiCorp Vault and OpenBao. OpenBao is patched. Vault remains exposed
OpenBao engineers at ControlPlane have chained 4 vulnerabilities to show how under certain conditions, an OpenBao or Vault server can be completely compromised from an unauthenticated position. This is only the second RCE ever found in the Vault codebase. The exploit is highly plausible in real-world environments, requiring only an unauthenticated entry path and a defined Raft snapshot policy to trigger a complete server compromise. If you are impacted, upgrade as soon as possible to OpenBao 2.6.3 or 2.7.0 While OpenBao is fully patched, HashiCorp Vault remains exposed as of writing. Unfortunately, IBM's unwillingness to coordinate a mutual disclosure policy means Vault users currently lack an official mitigation submitted by /u/the_hypotenuse [link] [ ]
