When processing local inter-process communication (IPC) storage callbacks, the service accepts and registers session structures including administrative role permissions, user identifiers, and authorization flags—without verifying the identity or authenticity of the sending process. An attacker can obtain elevated administrative privileges on the web management interface without legitimate authentication.","published_at":"2026-10-08T04:16:03.566000Z","last_modified_at":"2026-10-14T19:33:18.963000Z","cvss_v3_score":7.8,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":8.5,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-306"],"nvd_references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39164"],"vuln_status":"Analyzed","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-10-08T07:37:29.208922Z","updated_at":"2026-10-15T05:15:06.890595Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"broadcom","vendor_name":"Broadcom","product_slug":"fabric-operating-system","product_name":"fabric_operating_system","version_start":null,"version_start_inclusive":null,"version_end":"9.2.2d","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:o:broadcom:fabric_operating_system:*:*:*:*:*:*:*:*"},{"vendor_slug":"brocade","vendor_name":"Brocade","product_slug":"fabric-os","product_name":"Fabric OS","version_start":"0","version_start_inclusive":true,"version_end":"9.2.2d","version_end_inclusive":false,"cpe23_uri":"cve5:brocade:fabric-os:0:9.2.2d"},{"vendor_slug":"brocade","vendor_name":"Brocade","product_slug":"fabric-os","product_name":"Fabric OS","version_start":"10.0.0","version_start_inclusive":true,"version_end":"10.0.0a1","version_end_inclusive":true,"cpe23_uri":"cve5:brocade:fabric-os:10.0.0:10.0.0a1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://support.broadcom.com/external/content/SecurityAdvisories/0/39164","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-10-08T04:16:03.566000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-10-15T05:15:06.890595Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-10-15T05:15:06.890595Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-10-15T05:15:06.890595Z","label":"CVSS score revised","source":"nvd"}]}
