GHSA-prpj-rchp-9j5h OpenBao allows cancellation of root rekey and recovery rekey operations without authentication

• Go github.com/openbao/openbao: < 2.3.1 (no fix yet) • Go github.com/openbao/openbao: < 0.0.0-20250625150133-fe75468822a2 → fixed in 0.0.0-20250625150133-fe75468822a2

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, 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.
