When configuring Federated Authentication (FA), the system fails to sanitize the Identity Provider (IdP) issuer parameter. An authenticated administrator—or an attacker capable of supplying crafted FA configuration files during an import routine—can inject arbitrary web server directives. This can lead to service denial by preventing the web management daemon from starting, or potentially alter web server security controls.","categories":["Unclassified"],"product":"Fabric OS","vendor":"Brocade","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-87678","source_modified_at":"2026-10-08T13:03:41.761Z","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-2026-87678","source_modified_at":"2026-10-08T13:03:41.761Z","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":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.09406,"score_date":"2026-10-23"},"published_at":"2026-10-08T02:45:13.498Z","modified_at":"2026-10-08T13:03:41.761Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-87678","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T13:03:41.761Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-87678","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/0/39138"}],"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":"2026-10-08T13:03:16.326477Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-08T13:03:41.761Z","content_hash":"ab9b3ec8388b082d04a968c0f0c8e0b684304521aebb554a7b0e88c69df9e233"}}
