  "details" : "### Impact\n\nOpenBao before v2.3.0 and HashiCorp Vault as of the current v1.19.5 may leak sensitive information in logs when processing malformed data. 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",
