Summary
Wirtualna Uczelnia is vulnerable to Reflected Cross‑Site Scripting (XSS) due to insecure handling of the locale parameter across multiple endpoints. An attacker can craft a malicious URL with JavaScript embedded in the locale parameter and send it to a victim. When the victim opens the link, the injected script will be executed in their browser. This issue affects Wirtualna Uczelnia versions up to wu#2016.437.295#0#20260327_105545
