CVE-2026-31072

The JSONSerializer and CBORSerializer in APScheduler (all versions including 3.10.x and 4.0.0a5) are vulnerable to Remote Code Execution (RCE) via Insecure Deserialization. The unmarshal_object function allows for arbitrary class instantiation and state injection by dynamically importing modules and calling __setstate__ on any class available in the Python environment. An attacker can exploit this by submitting a specially crafted JSON or CBOR payload to an application using these serializers

Summary
  • (es) Los JSONSerializer y CBORSerializer en APScheduler (todas las versiones, incluidas la 3.10.x y la 4.0.0a5) son vulnerables a la Ejecución Remota de Código (RCE) a través de la Deserialización Insegura. La función unmarshal_object permite la instanciación arbitraria de clases y la inyección de estado importando módulos dinámicamente y llamando a __setstate__ en cualquier clase disponible en el entorno Python. Un atacante puede explotar esto enviando una carga útil JSON o CBOR especialmente diseñada a una aplicación que utilice estos serializadores.
