CVE-2025-57769
Full vulnerability record from the local CVENow database.
Description
FreshRSS is a free, self-hostable RSS aggregator. Versions 1.26.3 and below contain a vulnerability where a specially crafted page can trick a user into executing arbitrary JS code or promoting a user in FreshRSS by obscuring UI elements in iframes. If embedding an authenticated iframe is possible, this may lead to privilege escalation via obscuring the promote user button in the admin UI or XSS by tricking the user to drag content into the UserJS text area. This is fixed in version 1.27.0

"value": "FreshRSS es un agregador RSS gratuito y autoalojable. Las versiones 1.26.3 e inferiores contienen una vulnerabilidad donde una página especialmente diseñada puede engañar a un usuario para que ejecute código JS arbitrario o para promocionar a un usuario en FreshRSS al ocultar elementos de la interfaz de usuario en iframes. Si es posible incrustar un iframe autenticado, esto puede conducir a una escalada de privilegios mediante la ocultación del botón de promoción de usuario en la interfaz de administración o XSS al engañar al usuario para que arrastre contenido al área de texto de UserJS. Esto está corregido en la versión 1.27.0."
