CVE-2025-32015

FreshRSS is a self-hosted RSS feed aggregator. Prior to version 1.26.2, HTML is sanitized improperly inside the `<iframe srcdoc>` attribute, which leads to cross-site scripting (XSS) by loading an attacker's UserJS inside `<script src>`. In order to execute the attack, the attacker needs to control one of the victim's feeds and have an account on the FreshRSS instance that the victim is using. An attacker can gain access to the victim's account by exploiting this vulnerability. If the victim is an admin it would be possible to delete all users (cause damage) or execute arbitrary code on the server by modifying the update URL using fetch() via the XSS. Version 1.26.2 contains a patch for the issue.

Summary
  • (es) FreshRSS es un agregador de feeds RSS autoalojado. Antes de la versión 1.26.2, el HTML se depuraba incorrectamente dentro del atributo ``, lo que provocaba ataques de Cross-Site Scripting (XSS) al cargar el UserJS de un atacante dentro de `&lt;script src&gt;`. Para ejecutar el ataque, el atacante necesita controlar uno de los feeds de la víctima y tener una cuenta en la instancia de FreshRSS que esta utiliza. Un atacante puede acceder a la cuenta de la víctima aprovechando esta vulnerabilidad. Si la víctima es administrador, podría eliminar todos los usuarios (causar daños) o ejecutar código arbitrario en el servidor modificando la URL de actualización con fetch() mediante el XSS. La versión 1.26.2 incluye un parche para este problema.
