CVE-2026-34906

Server-Side Template Injection (SSTI) in Wirtualna Uczelnia allows an unauthenticated attacker to perform Remote Code Execution (RCE). In the endpoint redirectToUrl and parameter redirectUrlParameter, insufficient input validation permits injection of arbitrary template expressions that are executed on the server. Successful exploitation can allow an attacker to run remote commands, including establishing a reverse shell. This issue affects Wirtualna Uczelnia versions up to wu#2016.437.295#0#20260327_105545
