## Technical details

IBM TRIRIGA Application Platform is vulnerable to a stored cross-site scripting (XSS) vulnerability (CWE-79) within its Web UI. An authenticated attacker with low privileges can inject arbitrary JavaScript code that executes in the context of other users' browser sessions. This occurs due to improper neutralization of user-supplied input during web page generation. Successful exploitation can lead to the disclosure of sensitive session information or credentials. The vulnerability is addressed in IBM TRIRIGA Application Platform 5.0.4 GA, which implements a holistic approach to XSS mitigation.
