CVE-2025-12140Network attack vector

Unauthenticated RCE via Java expression evaluation

Published Nov 27, 2025 · Updated Nov 28, 2025

Eval injection in Wirtualna Uczelnia allows remote attackers to execute arbitrary code through an unauthenticated web request. The redirectToUrl endpoint passes the redirectUrlParameter value to a Java-expression interpreter without neutralizing executable directives. No authentication or user interaction is required, and successful evaluation grants code execution in the application server context.
