CVE-2026-40252

FastGPT is an AI Agent building platform. Prior to 4.14.10.4, Broken Access Control vulnerability (IDOR/BOLA) allows any authenticated team to access and execute applications belonging to other teams by supplying a foreign appId. While the API correctly validates the team token, it does not verify that the requested application belongs to the authenticated team. This leads to cross-tenant data exposure and unauthorized execution of private AI workflows. This vulnerability is fixed in 4.14.10.4.

Summary		(es) FastGPT es una plataforma de creación de agentes de IA. Antes de la versión 4.14.10.4, la vulnerabilidad de control de acceso roto (IDOR/BOLA) permite a cualquier equipo autenticado acceder y ejecutar aplicaciones pertenecientes a otros equipos al proporcionar un appId ajeno. Aunque la API valida correctamente el token del equipo, no verifica que la aplicación solicitada pertenezca al equipo autenticado. Esto conduce a la exposición de datos entre inquilinos y a la ejecución no autorizada de flujos de trabajo de IA privados. Esta vulnerabilidad está corregida en la versión 4.14.10.4.
