CVE-2026-46358
OpenBao's Inline Auth Incorrectly Redacted Headers
Description
### 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. ### Resources https://github.com/openbao/openbao/issues/3074
