The internal gate guarding restricted management endpoints relies exclusively on client-controlled HTTP headers. An authenticated user with any valid REST session can spoof these headers to gain unauthorized access to internal management endpoints. This allows low-privilege users to view sensitive chassis metadata, hardware memory patrolling state, and firmware integrity audit logs.","state":0,"publishedAt":"2026-10-08T02:51:42.116+00:00","modifiedAt":"2026-10-08T13:15:50.338+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:N/VA:N/SC:N/SI:N/SA:N","score":5.1,"severity":"MEDIUM"}],"references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39140"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87670","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87670","identifiers":["CVE-2026-87670"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
