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 due to cross-site scripting. HTML content supplied by a provider is not sufficiently sanitized before it is displayed, which could allow script content to run in the user's browser.
