CVE-2025-10975Public exploitNetwork attack vector

Remote code execution via unsafe pickle deserialization

Published Sep 25, 2025 · Updated Sep 25, 2025

Unsafe deserialization in vlarl at 31abc0baf53ef8f5db666a1c882e1ea64def2997 allows remote authenticated users to execute code via ZeroMQ messages. The run_reasoning_server function passes each received message directly to pickle.loads, so a crafted pickle invokes attacker-selected callables during deserialization. Network access to the ZeroMQ service and low privileges are required; successful exploitation runs code in the server process context.
