When handling concurrent incoming network management FCIP requests, a timing window exists between when a request populates the address variable and when the service constructs and returns the response context. As a result, the first request adopts the modified context, causing the service to return sensitive management details or configuration data belonging to the second context back to the original requester.\n\n## Affected\n\n- `fabric_operating_system < 10.0.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `fabric_operating_system 10.0.1`","depth":"sunlit","depthScore":14,"depthScoreParts":{"impact":14.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":220190,"id":"CVE-2026-94583","ts":1791992229812,"field":"cvss","old":"2.1","new":"2.6"}]}
