Technical details

A Reflected Cross-Site Scripting (XSS) vulnerability exists in Webbeyaz Web Design Mediküm Web through version 08072026. The flaw stems from the application's failure to properly sanitize user-supplied input before including it in dynamically generated web pages (CWE-79). An unauthenticated remote attacker can exploit this by tricking a user into visiting a malicious URL containing a crafted payload. Successful exploitation allows the execution of arbitrary JavaScript in the context of the victim's browser session. The vendor has confirmed the product is end-of-life (EOL) and no patch is expected.
