When processing certain management protocol operations, the RBAC engine incorrectly categorizes non-standard action opcodes during permission checks. This allows authenticated users with read-only management privileges to bypass access controls and execute restricted administrative operations.","state":0,"publishedAt":"2026-10-08T00:57:36.385+00:00","modifiedAt":"2026-10-08T13:41:19.896+00:00","affected":[{"ecosystem":"Vendor product","name":"Fabric OS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Brocade\",\n                    \"product\": \"Fabric OS\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"10.0.1\",\n                            \"versionType\": \"Brocade FabricOS\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"}],"references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39075"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87681","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87681","identifiers":["CVE-2026-87681"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
