astGPT is an AI Agent building platform. From 4.14.0 to 4.14.5, attackers can directly access the plugin system through FastGPT/api/plugin/xxx without authentication, thereby threatening the plugin system. This may cause the plugin system to crash and the loss of plugin installation status, but it will not result in key leakage. For older versions, as there are only operation interfaces for obtaining information, the impact is almost negligible. This vulnerability is fixed in 4.14.5-fix.

Summary
  • (es) FastGPT es una plataforma de creación de agentes de IA. Desde la 4.14.0 hasta la 4.14.5, los atacantes pueden acceder directamente al sistema de plugins a través de FastGPT/API/plugin/xxx sin autenticación, amenazando así el sistema de plugins. Esto puede causar que el sistema de plugins falle y la pérdida del estado de instalación del plugin, pero no resultará en una fuga de claves. Para versiones anteriores, ya que solo hay interfaces de operación para obtener información, el impacto es casi insignificante. Esta vulnerabilidad está corregida en la 4.14.5-fix.
