What changed

CERT-Bund published advisory WID-SEC-2026-1157 disclosing critical vulnerabilities in IBM App Connect Enterprise. The vulnerabilities affect multiple product versions across Certified Container and traditional deployment models with CVSS scores reaching 10.0 (critical).

Affected platforms include UNIX, Windows, and other operating systems.
