Title
OSCAL-GUI Reflected XSS via project parameter in oscal.php
Summary
OSCAL-GUI contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript in a victim's browser by injecting malicious input through the project request parameter. Attackers can craft a malicious URL containing unsanitized input that breaks out of the JavaScript string and HTML attribute context in the body onload event handler to execute arbitrary scripts when the link is visited by a victim.
