What is CVE-2026-34907?

Wirtualna Uczelnia exhibits a vulnerability that allows for Reflected Cross-Site Scripting (XSS) due to the insecure handling of the 'locale' parameter across several endpoints. An attacker can exploit this vulnerability by crafting a malicious URL embedded with JavaScript within the locale parameter.
