Upgrade Alpine:3.22 openbao to version 2.3.1-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openbao package and not the openbao package as distributed by Alpine.
See How to fix? for Alpine:3.22 relevant fixed versions and status.
OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. OpenBao before v2.3.0 may leak sensitive information in logs when processing malformed data. This is separate from the earlier HCSEC-2025-09 / CVE-2025-4166. This issue has been fixed in OpenBao v2.3.0 and later. Like with HCSEC-2025-09, there is no known workaround except to ensure properly formatted requests from all clients.
