CVE-2024-28761Network attack vector

Authenticated browser code execution via HTML injection

Published May 11, 2024 · Updated Mar 13, 2025

HTML injection in IBM App Connect Enterprise allows remote authenticated users to execute crafted HTML in a victim's browser. The Admin API and Dashboard render attacker-supplied content as active HTML instead of neutralizing it; IBM has not disclosed the specific request field or code path. Exploitation requires low-privileged access and a second user's interaction, and successful execution is confined to that viewer's hosting-site security context.
