### Impact When running in the highly privileged recovery mode, OpenBao was vulnerable to a timing attack against the single recovery token. This allowed an attacker to extract the recovery token and use it to perform operations against the OpenBao instance, including reading or modification of data. ### Patches This has been patched in OpenBao v2.6.0.
