{"id":"CVE-2025-62705","aliases":["BIT-openbao-2025-62705","GHSA-rc54-2g2c-g36g","GO-2025-4052"],"url":"https://o3.security/vulnerability/CVE-2025-62705","summary":"OpenBao and Vault Leak []byte Fields in Audit Logs","details":"### Impact\n\nOpenBao'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:\n\n- `sys/raw` with use of `encoding=base64`, all data would be emitted unredacted to the audit log.\n- Transit, when performing a signing operation with a derived Ed25519 key, would emit public keys to the audit log.\n\nThird-party plugins may be affected.\n\nThis issue has been present since HashiCorp Vault and continues to impact Vault as of v1.20.4. \n\n### Patches\n\nOpenBao v2.4.2 will patch this issue.\n\n### Workarounds\n\nIf 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.","published":"2025-10-22T21:23:51.631Z","modified":"2026-10-28T02:31:00.027444001Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/openbao/openbao","fixedVersion":"0.0.0-20251022165510-cc2c476bac66"}],"fix":{"url":"https://github.com/openbao/openbao/commit/cc2c476bac66e1d94776c2629793daec3af625f8","label":"openbao/openbao@cc2c476"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/62xxx/CVE-2025-62705.json"},{"type":"ADVISORY","url":"https://github.com/openbao/openbao/security/advisories/GHSA-rc54-2g2c-g36g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-62705"},{"type":"FIX","url":"https://github.com/openbao/openbao/commit/cc2c476bac66e1d94776c2629793daec3af625f8"},{"type":"PACKAGE","url":"https://github.com/openbao/openbao"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:00.027444001Z"}}
