Description
Impact
OpenBao's audit log experienced a regression wherein raw HTTP bodies used by few endpoints were not correctly redacted (HMAC'd). This impacted the following subsystems:
- When using the ACME functionality of PKI, this would result in short-lived ACME verification challenge codes being leaked in the audit logs.
- When using the OIDC issuer functionality of the identity subsystem, auth and token response codes along with claims could be leaked in the audit logs.
Third-party plugins may be affected.
Patches
OpenBao v2.4.2 will patch this issue.
Workarounds
If users do not use the above functionality, they are not impacted. ACME verification codes are not usable after verification or challenge expiry so are of limited long-term use.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-532: Insertion of Sensitive Information into Log File
The product writes sensitive information to a log file.
How to prevent it
- Architecture and Design, Implementation: Consider seriously the sensitivity of the information written into log files. Do not write secrets into the log files.
- Distribution: Remove debug log files before deploying the application into production.
- Operation: Protect log files against unauthorized read/write.
- Implementation: Adjust configurations appropriately when software is transitioned from a debug state to production.
