CVE-2025-62703

CVE-2025-62703 affects Fugue up to version 0.9.2, where the RPC server’s FlaskRPCServer decodes data with cloudpickle.loads() without sanitization, enabling remote code execution through crafted pickle payloads. The issue lies in the _decode() function in fugue/rpc/flask.py, allowing deserializat...

Fugue is Vulnerable to Remote Code Execution by Pickle Deserialization via FlaskRPCServer

Summary The Fugue framework implements an RPC server system for distributed computing operations. In the core functionality of the RPC server implementation, I found that the decode function in fugue/rpc/flask.py directly uses cloudpickle.loads to deserialize data without any sanitization. This...
