{"cve":"CVE-2026-46405","nvd":{"published":"2026-08-07T22:16:58.600","modified":"2026-09-09T21:02:22.660","status":"Deferred","description":"OpenBao is an open source identity-based secrets management system. Prior to version 2.5.4, in OpenBao's Kerberos auth method on the `GET` handler, or when an `Authorization: Negotiate` header is supplied, the response is includes a `logical.Auth` object in addition to an error message. This results in tokens being created with only the default policy, default TTL, and no entity information, which are hidden by the returned error message. No access to these tokens by the caller occurs and the authentication token is not ever made accessible outside of `sys/raw`. This is fixed in OpenBao v2.5.4. As a workaround, users may set a rate limit quota to limit the creation of these paths. As the path is unauthenticated, it isn't possible to deny access to it.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-770"],"references":["https://github.com/openbao/openbao/commit/0d82e0a5a3b6a93e8087bcbaf0b11326c12d4f4d","https://github.com/openbao/openbao/pull/3150","https://github.com/openbao/openbao/releases/tag/v2.5.4","https://github.com/openbao/openbao/security/advisories/GHSA-7j6w-vvw2-5f9c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-46405","score":0.00617,"percentile":0.49574,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7j6w-vvw2-5f9c","url":"https://osv.dev/vulnerability/GHSA-7j6w-vvw2-5f9c","summary":"OpenBao's Kerberos Auth Method Accumulates Unaccessible Tokens","modified":"2026-08-17T08:10:32.639007035Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","ranges":["<2.5.4"],"fixed":["2.5.4"]}]},{"id":"GO-2026-5225","url":"https://osv.dev/vulnerability/GO-2026-5225","summary":"OpenBao's Kerberos Auth Method Accumulates Unaccessible Tokens in github.com/openbao/openbao","modified":"2026-08-17T08:10:32.639007035Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","ranges":["all versions"],"fixed":[]}]}],"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).
