{"id":"CVE-2026-126312","summary":"OpenBao before 2.6.5 and 2.7.2 ACL Bypass via Non-Canonical Plugin Paths","details":"OpenBao before 2.6.5 and 2.7.x before 2.7.2, and the openbao-plugins LDAP and RADIUS auth plugins before 0.2.0, contain an ACL bypass in the AppRole, Cert, LDAP, and RADIUS auth methods caused by implicit path canonicalization. Authenticated attackers can request non-canonical paths for AppRole Role IDs, Cert CRLs, LDAP groups and users, or RADIUS users to evade ACL deny rules.","aliases":["GHSA-736f-82w7-hj22"],"modified":"2026-11-14T02:47:27.702126860Z","published":"2026-11-13T09:36:17.584Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-178"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126312.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126312.json"},{"type":"ADVISORY","url":"https://github.com/openbao/openbao/security/advisories/GHSA-736f-82w7-hj22"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-126312"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openbao-before-2.6.5-and-2.7.2-acl-bypass-via-non-canonical-plugin-paths"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openbao/openbao","events":[{"introduced":"0"},{"fixed":"b814361ea23440b881b43882e9d1bd950342471c"},{"fixed":"fb730b62a40e6cc4fc8e2f0257c673454bca3b86"},{"introduced":"ca305a02daa68b203325daa1b25c18d7a252d4b3"},{"fixed":"9e0a0d3c3504a0a00b45e61355afac5e35c78379"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"0"},{"fixed":"2.6.5"}],"source":"AFFECTED_FIELD"},{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"fixed":"0.2.0"}]},{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"2.7.0"},{"fixed":"2.7.2"}]}]}}],"versions":["v2.6.4","v2.7.1","api/v2.7.1","v2.7.0","v2.6.3","sdk/v2.6.3","v2.6.2","v2.6.1","sdk/v2.6.2","v2.6.0","sdk/v2.6.1","v2.6.0-beta20260622","sdk/v2.6.0","api/v2.6.0","api/auth/userpass/v2.6.0","api/auth/ldap/v2.6.0","api/auth/kubernetes/v2.6.0","api/auth/jwt/v2.6.0","api/auth/approle/v2.6.0","v2.5.0-beta20251125","sdk/v2.5.0","api/v2.5.0","api/auth/userpass/v2.5.0","api/auth/ldap/v2.5.0","api/auth/kubernetes/v2.5.0","api/auth/jwt/v2.5.0","api/auth/approle/v2.5.0","v2.4.0","sdk/v2.4.0","api/v2.4.0","api/auth/userpass/v2.4.0","api/auth/ldap/v2.4.0","api/auth/kubernetes/v2.4.0","api/auth/jwt/v2.4.0","api/auth/approle/v2.4.0","v2.3.0-beta20250528","sdk/v2.3.0","api/v2.3.0","api/auth/userpass/v2.3.0","api/auth/ldap/v2.3.0","api/auth/kubernetes/v2.3.0","api/auth/approle/v2.3.0","dev-namespaces-base-20250424","dev-namespaces-base-20250311","v2.2.0-beta20250213","dev-namespaces-base-20250215","sdk/v2.2.0","api/v2.2.0","api/auth/userpass/v2.2.0","api/auth/ldap/v2.2.0","api/auth/kubernetes/v2.2.0","api/auth/approle/v2.2.0","v2.1.0-beta20241114.3","v2.1.0-beta20241114.2","v2.1.0-beta20241114.1","v2.1.0-beta20241114","sdk/v2.1.0","api/v2.1.0","v2.0.0","sdk/v2.0.1","api/v2.0.1","api/auth/userpass/v2.0.1","api/auth/ldap/v2.0.1","api/auth/kubernetes/v2.0.1","api/auth/approle/v2.0.1","v2.0.0-beta20240618","sdk/v1.100.0-development20240408","api/v1.100.0-development20240408","api/auth/userpass/v1.1.0-development20240408","api/auth/ldap/v1.1.0-development20240408","api/auth/kubernetes/v1.1.0-development20240408","api/auth/gcp/v1.1.0-development20240408","api/auth/azure/v1.1.0-development20240408","api/auth/aws/v1.1.0-development20240408","api/auth/approle/v1.1.0-development20240408","v2.0.0-alpha20240329","before-plugin-removal","api/auth/userpass/v0.4.1","api/auth/gcp/v0.4.1","api/auth/azure/v0.4.1","api/auth/aws/v0.4.1","api/auth/approle/v0.4.1","sdk/v0.9.1","api/v1.9.2","api/v1.9.1","sdk/v0.9.0","api/auth/userpass/v0.4.0","api/auth/gcp/v0.4.0","api/auth/azure/v0.4.0","api/auth/aws/v0.4.0","api/auth/approle/v0.4.0","sdk/v0.8.0","api/v1.9.0","api/v1.8.3","sdk/v0.7.0","sdk/v0.6.2","sdk/v0.6.1","api/v1.8.2","api/v1.8.1","api/auth/userpass/v0.3.0","api/auth/gcp/v0.3.0","api/auth/azure/v0.3.0","api/auth/aws/v0.3.0","api/auth/approle/v0.3.0","api/v1.8.0","sdk/v0.6.0","api/auth/userpass/v0.2.0","api/auth/gcp/v0.2.0","api/auth/azure/v0.2.0","api/auth/aws/v0.2.0","api/auth/approle/v0.2.0","sdk/v0.5.3","api/v1.7.2","sdk/v0.5.1","api/v1.7.1","api/v1.7.0","api/v1.6.0","sdk/v0.5.0","api/v1.5.0","sdk/v0.4.1","api/v1.3.1","api/auth/approle/v0.1.1","api/auth/gcp/v0.1.0","api/auth/azure/v0.1.0","api/auth/userpass/v0.1.0","api/auth/aws/v0.1.0","api/auth/approle/v0.1.0","sdk/v0.3.0","api/v1.2.0","api/v1.1.1","sdk/v0.2.1","api/v1.0.4","sdk/v0.1.13","api/v1.0.3","sdk/v0.1.12","sdk/v0.1.11","sdk/v0.1.10","api/v1.0.2","sdk/v0.1.9","api/v1.0.1","sdk/v0.1.8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-126312.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
