CVE-2026-33235

Full vulnerability record from the local CVENow database.

Description

AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. In versions prior to 0.6.52, the Fill Text Template block is vulnerable to a Denial of Service (DoS) attack. While the backend implements a SandboxedEnvironment to prevent unauthorized attribute access (e.g., blocking __class__), it fails to limit the computational complexity or execution time of the expressions. An attacker can input computationally expensive Python/Jinja2 expressions that consume the server's CPU and memory, leading to a complete system hang or crash. In multi-tenant or self-hosted environments, this results in a complete service outage and "noisy neighbor" effects that require manual administrative intervention to recover. This issue has been fixed in version 0.6.52.

      "value": "AutoGPT es una plataforma de automatización de flujos de trabajo para crear, desplegar y gestionar agentes de inteligencia artificial continuos. En versiones anteriores a la 0.6.52, el bloque Fill Text Template es vulnerable a un ataque de denegación de servicio (DoS). Aunque el backend implementa un SandboxedEnvironment para prevenir el acceso no autorizado a atributos (p. ej., bloqueando __class__), no logra limitar la complejidad computacional o el tiempo de ejecución de las expresiones. Un atacante puede introducir expresiones Python/Jinja2 computacionalmente costosas que consumen la CPU y la memoria del servidor, lo que lleva a un bloqueo o caída completa del sistema. En entornos multi-inquilino o autoalojados, esto resulta en una interrupción completa del servicio y efectos de ’vecino ruidoso’ que requieren intervención administrativa manual para recuperarse. Este problema ha sido solucionado en la versión 0.6.52."
