CVE-2025-52894 Details
Description
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.
A denial-of-service vulnerability has been identified in OpenBao versions prior to 2.3.0. The issue allows an attacker to perform unauthenticated and unaudited cancellations of root rekey and recovery rekey operations. This vulnerability disrupts valid rekey processes and is not logged or monitored, leaving a gap in operational awareness.
Users can update to OpenBao version 2.3.0 or later, where this vulnerability is patched. Additionally, the configuration option `disable_unauthed_rekey_endpoints=true` can be manually set to disable unauthenticated rekey endpoints on global listeners. In a future OpenBao release, this option will be set to true by default for all users.
