Technical details
A reflected Cross-Site Scripting (XSS) vulnerability exists in FoxCMS version 1.2.6 within the '/index.php/plus' endpoint. The application fails to properly neutralize user-supplied input before including it in the generated web page (CWE-79). An unauthenticated remote attacker can exploit this by sending a crafted URL to a victim. If the victim visits the link, the attacker's malicious JavaScript will execute in the context of the victim's browser session, potentially leading to session hijacking or unauthorized data access. A proof-of-concept has been identified in public disclosures.
