NewCVE-2025-62703 (opens in a new tab)How to fix?
There is no fixed version for fugue.
Overview
fugue is an An abstraction layer for distributed computation
Affected versions of this package are vulnerable to Command Injection via the _decode function, which invokes cloudpickle.loads() on untrusted data. An attacker can execute arbitrary code on the server by sending specially crafted serialized data to the RPC server on the network.
Workaround
This vulnerability can be mitigated by replacing unsafe deserialization methods with safer alternatives, such as using JSON serialization for simple data, Protocol Buffers or MessagePack for complex data, or implementing a custom Unpickler with restricted class loading.
Additionally, binding the service to localhost and implementing authentication and authorization mechanisms can reduce exposure.
