CVE-2026-75624Network attack vector

Privilege escalation and service disruption via incorrect authorization

Published Sep 10, 2026 · Updated Sep 10, 2026

Incorrect authorization in IBM App Connect Enterprise allows remote authenticated users to bypass security restrictions. IBM identifies the runtime as the affected component but has not published the authorization check, protected operation, or request path that is mishandled. Authenticated network access is required across versions 12.0.1.0 through 12.0.12.27 and 13.0.1.0 through 13.0.8.1; exploitation raises privileges and can deny service, but IBM does not specify the interruption mode.
