Unauthenticated HTTP endpoints process specific URL query parameters without validating array index boundaries or performing numerical range checks. An unauthenticated remote attacker can exploit this issue by sending a single, crafted HTTP request containing extreme numerical values in the query string. This causes an invalid memory dereference, resulting in a crash of the web management process (Denial of Service) and potential temporary management-plane disruption.","categories":["Unclassified"],"product":"Fabric OS","vendor":"Brocade","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-87671","source_modified_at":"2026-10-08T17:57:15.528Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Fabric OS","vendor":"Brocade","versions":[{"status":"affected","version":"0","lessThan":"10.0.1","versionType":"Brocade FabricOS"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-87671","source_modified_at":"2026-10-08T17:57:15.528Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Fabric OS","ecosystem":null},"version":"10.0.1","basis":"first unaffected version stated in the CVE record"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00398,"percentile":0.32823,"score_date":"2026-10-23"},"published_at":"2026-10-08T02:22:02.036Z","modified_at":"2026-10-08T17:57:15.528Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-87671","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T17:57:15.528Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-87671","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://support.broadcom.com/external/content/SecurityAdvisories/0/39141"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-08T14:57:22.906701Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-08T17:57:15.528Z","content_hash":"a894fea7bebec49ca4461d0cc51792d28fa712c7ce4dc81cb649776cee62e4fe"}}
