OpenBao before v2.3.0 may leak sensitive information in logs when processing malformed data. This is separate from the earlier HCSEC-2025-09 / CVE-2025-4166. This issue has been fixed in OpenBao v2.3.0 and later. Like with HCSEC-2025-09, there is no known workaround except to ensure properly formatted requests from all clients.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N","score":4.5},"cwes":["CWE-532"],"references":["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","https://github.com/go-viper/mapstructure/commit/ed3f92181528ff776a0324107b8b55026e93766a","https://github.com/go-viper/mapstructure/pull/105","https://github.com/go-viper/mapstructure/releases/tag/v2.3.0","https://github.com/openbao/openbao/commit/cf5e920badbf96b41253534a3fd5ff5063bf4b30"],"products":["openbao:openbao"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-52893","score":0.00327,"percentile":0.25787,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8f5r-8cmq-7fmq","url":"https://osv.dev/vulnerability/GHSA-8f5r-8cmq-7fmq","summary":"OpenBao Inserts Sensitive Information into Log File when processing malformed data","modified":"2026-07-27T09:11:30.619968656Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao/sdk/v2","purl":"pkg:golang/github.com/openbao/openbao/sdk/v2","ranges":["<2.3.0"],"fixed":["2.3.0"]}]},{"id":"GO-2025-3780","url":"https://osv.dev/vulnerability/GO-2025-3780","summary":"OpenBao Inserts Sensitive Information into Log File when processing malformed data in github.com/openbao/openbao/sdk","modified":"2026-07-27T09:11:30.619968656Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao/sdk","purl":"pkg:golang/github.com/openbao/openbao/sdk","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/openbao/openbao/sdk/v2","purl":"pkg:golang/github.com/openbao/openbao/sdk/v2","ranges":["<2.3.0"],"fixed":["2.3.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
