Authenticated information disclosure via authorization-schema bypass

Published Apr 15, 2020 · Updated Aug 4, 2024

Access-control bypass in Broadcom Layer7 API Developer Portal 4.3.1 and earlier allows remote authenticated users to view restricted data. The vendor identifies an authorization-schema bypass but does not disclose the affected endpoint, data object, or failed permission check. A valid privileged account is required, and the reported consequence is limited to reading data that the assigned role should not expose.
