CVE-2024-49375Public exploitNetwork attack vector

Remote code execution via unsafe model deserialization

Published Jan 14, 2025 · Updated Jan 15, 2025

Unsafe deserialization in affected Rasa Pro releases allows remote attackers to execute code by remotely loading a crafted model archive. Model loaders for TEDPolicy and other components pass attacker-controlled pickle and jsonpickle files from the archive to unsafe deserializers, which invoke embedded Python payloads. The HTTP API must be enabled, which is not the default; access is unauthenticated only when API authentication is absent, while configured token or JWT controls require valid credentials.
