CVE-2026-94575

Privilege escalation via web management RBAC bypass

Published Oct 8, 2026 · Updated Oct 8, 2026

Access control bypass in Brocade Communications Systems Fabric OS before 10.0.1 allows remote authenticated users to access admin-only settings. The Common Access Layer in the web management framework fails to enforce inner RBAC checks and lowers the authorization mode of the active session; Broadcom does not disclose the precise code path. Exploitation requires a low-privileged account, adjacent-network access, and environmental conditions that Broadcom has not specified.
