Unauthenticated RCE via pickle deserialization
Published Mar 18, 2026 · Updated Mar 18, 2026
Unsafe deserialization in OmniGen2-RL version 0 allows remote attackers to execute arbitrary commands via malicious HTTP POST requests. The proxy's prepare_request_data and worker's parse_and_validate_request functions pass raw request bodies to pickle.loads before validating the resulting objects. No authentication or user interaction is required; the proxy and workers bind to all interfaces by default, exposing host-level code execution to attackers with network access.
