CVE-2025-52894 (opens in a new tab)How to fix?
Upgrade Alpine:3.22 openbao to version 2.3.1-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openbao package and not the openbao package as distributed by Alpine.
See How to fix? for Alpine:3.22 relevant fixed versions and status.
OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. OpenBao before v2.3.0 allowed an attacker to perform unauthenticated, unaudited cancellation of root rekey and recovery rekey operations, effecting a denial of service. In OpenBao v2.2.0 and later, manually setting the configuration option disable_unauthed_rekey_endpoints=true allows an operator to deny these rarely-used endpoints on global listeners. A patch is available at commit fe75468822a22a88318c6079425357a02ae5b77b. In a future OpenBao release communicated on OpenBao's website, the maintainers will set this to true for all users and provide an authenticated alternative. As a workaround, if an active proxy or load balancer sits in front of OpenBao, an operator can deny requests to these endpoints from unauthorized IP ranges.
