Prior to 2.6.0, OpenBao's vault/policy/acl.go could evaluate a broader wildcard ACL grant before more-specific trailing-wildcard ACL paths with capabilities = [\"deny\"] for a LIST operation. When a parent path permitted LIST and a child path was denied, the trailing-slash lookup could therefore allow listing the denied path. Other operation types are outside the repository advisory's affected scope. This issue is fixed in version 2.6.0."}],"metrics":[{"cvssV4_0":{"attackComplexity":"LOW","attackRequirements":"PRESENT","attackVector":"NETWORK","baseScore":6,"baseSeverity":"MEDIUM","privilegesRequired":"LOW","subAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","userInteraction":"NONE","vectorString":"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","version":"4.0","vulnAvailabilityImpact":"NONE","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"NONE"}}],"problemTypes":[{"descriptions":[{"cweId":"CWE-863","description":"CWE-863: Incorrect Authorization","lang":"en","type":"CWE"}]}],"providerMetadata":{"dateUpdated":"2026-09-23T17:59:16.337Z","orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M"},"references":[{"name":"https://github.com/openbao/openbao/security/advisories/GHSA-xp3c-3jw3-4vcr","tags":["x_refsource_CONFIRM"],"url":"https://github.com/openbao/openbao/security/advisories/GHSA-xp3c-3jw3-4vcr"},{"name":"https://github.com/openbao/openbao/pull/3389","tags":["x_refsource_MISC"],"url":"https://github.com/openbao/openbao/pull/3389"},{"name":"https://github.com/openbao/openbao/pull/3474","tags":["x_refsource_MISC"],"url":"https://github.com/openbao/openbao/pull/3474"},{"name":"https://github.com/openbao/openbao/commit/2e9625d6cebe4639d051ef53dd6ce7c49914ae6a","tags":["x_refsource_MISC"],"url":"https://github.com/openbao/openbao/commit/2e9625d6cebe4639d051ef53dd6ce7c49914ae6a"},{"name":"https://github.com/openbao/openbao/commit/f58d848c139e5ba71aa63103fcfe101972b999fc","tags":["x_refsource_MISC"],"url":"https://github.com/openbao/openbao/commit/f58d848c139e5ba71aa63103fcfe101972b999fc"},{"name":"https://github.com/hashicorp/vault/blob/main/CHANGELOG.md#203","tags":["x_refsource_MISC"],"url":"https://github.com/hashicorp/vault/blob/main/CHANGELOG.md#203"},{"name":"https://github.com/openbao/openbao/releases/tag/v2.6.0","tags":["x_refsource_MISC"],"url":"https://github.com/openbao/openbao/releases/tag/v2.6.0"}],"source":{"advisory":"GHSA-xp3c-3jw3-4vcr","discovery":"UNKNOWN"},"title":"OpenBao LIST ACL bypass: a trailing-slash LIST request skips a more-specific deny rule (unported Vault v2.0.3 fix)"}},"cveMetadata":{"assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","assignerShortName":"GitHub_M","cveId":"CVE-2026-63131","datePublished":"2026-09-23T17:59:16.337Z","dateReserved":"2026-07-15T16:54:55.817Z","dateUpdated":"2026-09-23T17:59:16.337Z","state":"PUBLISHED"},"dataType":"CVE_RECORD","dataVersion":"5.2"}
