CVE-2026-94578

Root-equivalent chassis access via crafted AAA claims

Published Oct 8, 2026 · Updated Oct 8, 2026

Authorization bypass in Brocade Fabric OS before 10.0.1 allows remote authenticated users to gain root-equivalent chassis access. During session establishment, the AAA integration framework accepts crafted identity-provider attributes or directory claims without enforcing administrative role restrictions. Exploitation requires an account whose external identity-provider response supplies those claims.
