{"id":"GHSA-xp3c-3jw3-4vcr","summary":"OpenBao Skips Stricter Deny Policy for LIST operations","details":"## Impact\n\nWhen a policy operator has written `capabilities = [\"deny\"]` on a path with a trailing wildcard but allowed a broader list operation (e.g., a `deny` on `secrets/metadata/restricted/*` but allowed `list` on `secrets/metadata/*`), OpenBao would incorrectly allow the operation. This did not impact other operation types.\n\n## Patches\n\nThis has been patched in OpenBao v2.6.0.","aliases":["CVE-2026-63131"],"modified":"2026-09-22T21:00:11.403549509Z","published":"2026-09-22T20:36:56Z","database_specific":{"github_reviewed_at":"2026-09-22T20:36:56Z","nvd_published_at":null,"cwe_ids":["CWE-863"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/openbao/openbao/security/advisories/GHSA-xp3c-3jw3-4vcr"},{"type":"WEB","url":"https://github.com/openbao/openbao/pull/3389"},{"type":"WEB","url":"https://github.com/openbao/openbao/pull/3474"},{"type":"WEB","url":"https://github.com/openbao/openbao/commit/2e9625d6cebe4639d051ef53dd6ce7c49914ae6a"},{"type":"WEB","url":"https://github.com/openbao/openbao/commit/f58d848c139e5ba71aa63103fcfe101972b999fc"},{"type":"WEB","url":"https://github.com/hashicorp/vault/blob/main/CHANGELOG.md#203"},{"type":"PACKAGE","url":"https://github.com/openbao/openbao"},{"type":"WEB","url":"https://github.com/openbao/openbao/releases/tag/v2.6.0"}],"affected":[{"package":{"name":"github.com/openbao/openbao","ecosystem":"Go","purl":"pkg:golang/github.com/openbao/openbao"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20260713133043-f58d848c139e"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-xp3c-3jw3-4vcr/GHSA-xp3c-3jw3-4vcr.json"}},{"package":{"name":"github.com/openbao/openbao","ecosystem":"Go","purl":"pkg:golang/github.com/openbao/openbao"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.1.0"},{"last_affected":"1.1.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-xp3c-3jw3-4vcr/GHSA-xp3c-3jw3-4vcr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
