CVE-2025-62705
OpenBao and Vault Leak []byte Fields in Audit Logs
Impact
### Impact OpenBao's audit log did not appropriately redact fields when relevant subsystems sent `[]byte` response parameters rather than `string`s. This includes, but is not limited to: - `sys/raw` with use of `encoding=base64`, all data would be emitted unredacted to the audit log. - Transit, when performing a signing operation with a derived Ed25519 key, would emit public keys to the audit log. Third-party plugins may be affected. This issue has been present since HashiCorp Vault and continues to impact Vault as of v1.20.4. ### Patches OpenBao v2.4.2 will patch this issue. ### Workarounds If users do not use the above functionality, they are not impacted. To prohibit the use of `sys/raw` globally, ensure `raw_storage_endpoint=false` is set or missing from the server configuration.
