Summary
IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to execute arbitrary JavaScript in the victim's browser due to cross-site scripting. User-supplied input is not properly neutralized when a web page is updated, so script content could run in another user's session.
