The web dispatcher routine evaluates internal management VLAN trust decisions using the client-supplied HTTP host header instead of the actual socket transport layer source IP address. Successful exploitation allows the attacker to bypass IP-filtering access control lists (ACLs) and obtain sensitive device metadata (such as model, serial number, hardware revision, and firmware version) without authentication.","state":0,"publishedAt":"2026-10-08T02:31:52.669+00:00","modifiedAt":"2026-10-08T12:54:37.227+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:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"}],"references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39080"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87686","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87686","identifiers":["CVE-2026-87686"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
