MEDIUM 5.1EPSS 0.29%

Does this matter?

Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.

Description

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
