Technical details
Fifteen reflected cross-site scripting (CWE-79) vulnerabilities exist in various input parameters and endpoints of the Repasat application, affecting authenticated users who interact with crafted malicious links or forms. The vulnerabilities require network access and user interaction (a user clicking a malicious link or visiting an attacker-controlled page) but demand authentication to the application. Successful exploitation allows arbitrary JavaScript execution in the victim's browser context, potentially leading to session hijacking, credential theft, or unauthorized data modification.
