OpenBao's Inline Auth Incorrectly Redacted Headers

Impact

OpenBao's inline auth functionality incorrectly redacted audit log entries, resulting in non-auth headers being removed and auth-related headers being retained in cleartext. This requires an attacker to compromise access to the audit device. Operators should review leaked source authentication material and rotate it as appropriate.

Patches

This is fixed in OpenBao v2.5.4.
