An attacker with access to, and the ability to observe a large number of unseal operations on the host through a side channel may reduce the search space of a brute force effort to recover the Shamir shares. Fixed in Vault 1.13.1, 1.12.5, and 1.11.9.","published":"2023-03-30T00:17:46.230Z","modified":"2026-07-15T01:49:03.224026427Z","cvss":{"score":5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/hashicorp/vault","fixedVersion":"1.11.9"},{"ecosystem":"Go","name":"github.com/hashicorp/vault","fixedVersion":"1.12.5"},{"ecosystem":"Go","name":"github.com/hashicorp/vault","fixedVersion":"1.13.1"}],"fix":null,"references":[{"type":"WEB","url":"https://discuss.hashicorp.com/t/hcsec-2023-10-vault-vulnerable-to-cache-timing-attacks-during-seal-and-unseal-operations/52078"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25000.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-25000"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230526-0008/"},{"type":"PACKAGE","url":"https://github.com/hashicorp/vault"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:03.224026427Z"}}
