CVE-2025-52894
OpenBao allows cancellation of root rekey and recovery rekey operations without authentication
Impact
### Impact OpenBao and HashiCorp Vault allowed an attacker to perform unauthenticated, unaudited cancellation of root rekey and recovery rekey operations, effecting a denial of service. ### Patches In OpenBao v2.2.2 and later, manually setting the configuration option `disable_unauthed_rekey_endpoints=true` allows an operator to deny these rarely-used endpoints on global listeners. In a future OpenBao release [communicated on our website](https://openbao.org/docs/deprecation/), we will set this to `true` for all users and provide an authenticated alternative. This vulnerability has been disclosed to HashiCorp; see their website for more information. ### Workarounds If an active proxy or load balancer sits in front of OpenBao, an operator can deny requests to these endpoints from unauthorized IP ranges. ### References See the [deprecation notice](https://openbao.org/docs/deprecation/unauthed-rekey/).
