Summary
OpenBao has a Timing Side-Channel in the Userpass Auth Method
Details

Impact

When using OpenBao's userpass auth method, user enumeration was possible due to timing difference between non-existent users and users with stored credentials. This is independent of whether the supplied credentials were valid for the given user.

Patches

OpenBao v2.3.2 will patch this issue.

Workarounds

Users may use another auth method or apply rate limiting quotas to limit the number of requests in a period of time: https://openbao.org/api-docs/system/rate-limit-quotas/
