      "value": "Cross-Site Scripting (XSS) vulnerability exists in SourceCodester AI Font Matcher (nid=18425, 2025-10-10) that allows remote attackers to execute arbitrary JavaScript in victims' browsers. The vulnerability occurs in the webfonts API handling mechanism where font family names are not properly sanitized. An attacker can intercept fetch requests to the webfonts endpoint and inject malicious JavaScript payloads through font family names, resulting in session cookie theft, account hijacking, and unauthorized actions performed on behalf of authenticated users. The vulnerability can be exploited by injecting a fetch hook that returns controlled font data containing malicious scripts."

      "value": "Una vulnerabilidad de Cross-Site Scripting (XSS) existe en SourceCodester AI Font Matcher (nid=18425, 2025-10-10) que permite a atacantes remotos ejecutar JavaScript arbitrario en los navegadores de las víctimas. La vulnerabilidad se produce en el mecanismo de manejo de la API de webfonts donde los nombres de las familias de fuentes no se sanean correctamente. Un atacante puede interceptar solicitudes fetch al endpoint de webfonts e inyectar cargas útiles de JavaScript maliciosas a través de los nombres de las familias de fuentes, lo que resulta en robo de cookies de sesión, secuestro de cuentas y acciones no autorizadas realizadas en nombre de usuarios autenticados. La vulnerabilidad puede ser explotada inyectando un hook de fetch que devuelve datos de fuente controlados que contienen scripts maliciosos."
