This is separate from the earlier HCSEC-2025-09 / CVE-2025-4166. \n\n### Patches\n\nThis issue has been fixed in OpenBao v2.3.0 and later.\n\n### Workarounds\n\nLike with HCSEC-2025-09, there is no known workaround except to ensure properly formatted requests from all clients.\n\n### Remediation\n\nUsers with the capability to search through server and audit logs for any possible exposed secrets can refer to the following snippets to aid in searching:\n\nAudit Log\n\n```\n... \"error\":\"error converting input for field \\\"password\\\": expected type 'string', got unconvertible type 'map[string]interface {}', value: '<sensitive data>'\" ...\n```\n\nServer Log\n\n```\nerror converting input for field \"password\": expected type 'string', got unconvertible type 'map[string]interface {}', value: '<sensitive data>'\n```\n\nIf any matches are found, rotating the affected secret is advised.\n\n### References\n\nSee also: https://discuss.hashicorp.com/t/hcsec-2025-09-vault-may-expose-sensitive-information-in-error-logs-when-processing-malformed-data-with-the-kv-v2-plugin/74717\n\nSee also: https://github.com/go-viper/mapstructure/releases/tag/v2.3.0\n\nSee also: https://github.com/go-viper/mapstructure/pull/105 -> https://github.com/go-viper/mapstructure/commit/ed3f92181528ff776a0324107b8b55026e93766a","affected":[{"package":{"name":"github.com/openbao/openbao/sdk/v2","ecosystem":"Go","purl":"pkg:golang/github.com/openbao/openbao/sdk/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.3.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/06/GHSA-8f5r-8cmq-7fmq/GHSA-8f5r-8cmq-7fmq.json"}}],"references":[{"type":"WEB","url":"https://github.com/openbao/openbao/security/advisories/GHSA-8f5r-8cmq-7fmq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-52893"},{"type":"WEB","url":"https://github.com/go-viper/mapstructure/pull/105"},{"type":"WEB","url":"https://github.com/go-viper/mapstructure/commit/ed3f92181528ff776a0324107b8b55026e93766a"},{"type":"WEB","url":"https://github.com/openbao/openbao/commit/cf5e920badbf96b41253534a3fd5ff5063bf4b30"},{"type":"WEB","url":"https://discuss.hashicorp.com/t/hcsec-2025-09-vault-may-expose-sensitive-information-in-error-logs-when-processing-malformed-data-with-the-kv-v2-plugin/74717"},{"type":"WEB","url":"https://github.com/go-viper/mapstructure/releases/tag/v2.3.0"},{"type":"PACKAGE","url":"github.com/openbao/openbao/sdk/v2/framework"}],"database_specific":{"cwe_ids":["CWE-532"],"github_reviewed":true,"github_reviewed_at":"2025-06-26T21:25:00Z","nvd_published_at":"2025-06-25T17:15:39Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N"}]}
