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.
