CVE-2026-94576

Privilege escalation via partial authorization comparison

Published Oct 8, 2026 · Updated Oct 8, 2026

Authorization bypass in Brocade Fabric OS before 9.2.2d and 10.0.0 through 10.0.0a1 lets remote authenticated users grant administrative roles. The account management interface uses a partial comparison in an authorization check, allowing changes to another account's access privileges. Exploitation requires a lower-privileged account and specific conditions that Broadcom has not disclosed; the resulting privilege escalation is confined to the affected switch.
