CVE-2026-17416: IBM App Connect Enterprise insecure deserialization

CVE-2026-17416 · Severity: high · CVSS 7.8 · Published 2026-09-14

IBM App Connect Enterprise is an integration platform that connects business applications and data across an organization. A local attacker can execute arbitrary code on systems running affected versions (12.0.1.0–12.0.12.27 and 13.0.1.0–13.0.8.0) by exploiting insecure deserialization, potentially compromising the entire integration infrastructure and any connected systems.

Technologies: IBM App Connect Enterprise. Vendors: IBM.

Technical details

The vulnerability is a CWE-502 insecure deserialization flaw (CVE-2026-17416) in IBM App Connect Enterprise that allows arbitrary code execution. The attack vector is local (AV:L) with no privileges required (PR:N), but requires user interaction (UI:R). An attacker can craft malicious serialized objects that, when deserialized by the application, execute arbitrary code with the privileges of the process. Patches are available: version 13.0.8.1 and 12.0.12.28 include APAR IT49855.
