{"id":"CVE-2026-63131","published":"2026-09-23T19:17:34.497","lastModified":"2026-09-29T19:06:32.333","description":"OpenBao is an open source identity-based secrets management system. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://github.com/hashicorp/vault/blob/main/CHANGELOG.md#203","tags":[]},{"url":"https://github.com/openbao/openbao/commit/2e9625d6cebe4639d051ef53dd6ce7c49914ae6a","tags":[]},{"url":"https://github.com/openbao/openbao/commit/f58d848c139e5ba71aa63103fcfe101972b999fc","tags":[]},{"url":"https://github.com/openbao/openbao/pull/3389","tags":[]},{"url":"https://github.com/openbao/openbao/pull/3474","tags":[]},{"url":"https://github.com/openbao/openbao/releases/tag/v2.6.0","tags":[]},{"url":"https://github.com/openbao/openbao/security/advisories/GHSA-xp3c-3jw3-4vcr","tags":[]}],"exploitRefs":[{"url":"https://github.com/hashicorp/vault/blob/main/CHANGELOG.md#203","tags":[]},{"url":"https://github.com/openbao/openbao/commit/2e9625d6cebe4639d051ef53dd6ce7c49914ae6a","tags":[]},{"url":"https://github.com/openbao/openbao/commit/f58d848c139e5ba71aa63103fcfe101972b999fc","tags":[]},{"url":"https://github.com/openbao/openbao/pull/3389","tags":[]},{"url":"https://github.com/openbao/openbao/pull/3474","tags":[]},{"url":"https://github.com/openbao/openbao/releases/tag/v2.6.0","tags":[]},{"url":"https://github.com/openbao/openbao/security/advisories/GHSA-xp3c-3jw3-4vcr","tags":[]}],"hasPoc":true,"ai":null}
