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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-63131)\n\nAffected packages:\n\n- `github.com/openbao/openbao < 0.0.0-20260713133043-f58d848c139e`\n- `github.com/openbao/openbao >= 0.1.0, <= 1.1.5`\n\nPatched in:\n\n- `github.com/openbao/openbao 0.0.0-20260713133043-f58d848c139e`\n\nSource: https://github.com/advisories/GHSA-xp3c-3jw3-4vcr\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-63131.json)","depth":"sunlit","depthScore":33,"depthScoreParts":{"impact":33,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":209832,"id":"CVE-2026-63131","ts":1790188241514,"field":"cvss","old":null,"new":"6"}]}
