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 scripts due to cross-site scripting. Certain URL fields are not sufficiently validated, so malicious script content could run in another user's browser session.
