CVE-2024-0937Network attack vector

Arbitrary code execution via unsafe cloudpickle loading

Published Jan 26, 2024 · Updated Oct 18, 2024

Deserialization in SynthCity 0.2.9 and earlier allows attackers to execute arbitrary Python code through a crafted PKL file. The load_from_file function opens the supplied file and passes its contents directly to cloudpickle.load without validation or a restricted unpickler. Exploitation requires the library to load attacker-controlled serialized data; SynthCity does not expose this operation as a standalone network service.
