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.","affected":[{"package":{"name":"github.com/openbao/openbao","ecosystem":"Go","purl":"pkg:golang/github.com/openbao/openbao"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20251022165510-cc2c476bac66"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/10/GHSA-rc54-2g2c-g36g/GHSA-rc54-2g2c-g36g.json"}}],"references":[{"type":"WEB","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":"WEB","url":"https://github.com/openbao/openbao/commit/cc2c476bac66e1d94776c2629793daec3af625f8"},{"type":"PACKAGE","url":"https://github.com/openbao/openbao"}],"database_specific":{"cwe_ids":["CWE-532"],"github_reviewed":true,"github_reviewed_at":"2025-10-22T19:55:40Z","nvd_published_at":"2025-10-22T22:15:35Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
