CVE-2025-62703— fugue 代码问题漏洞

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

Fugue is a unified interface for distributed computing that lets users execute Python, Pandas, and SQL code on Spark, Dask, and Ray with minimal rewrites. In version 0.9.2 and prior, there is a remote code execution vulnerability by pickle deserialization via FlaskRPCServer. 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 creates a remote code execution vulnerability when malicious pickle data is processed by the RPC server. The vulnerability exists in the RPC communication mechanism where the client can send arbitrary serialized Python objects that will be deserialized on the server side, allowing attackers to execute arbitrary code on the victim's machine. This issue has been patched via commit 6f25326.

可信数据的反序列化

fugue 代码问题漏洞

fugue是The Fugue Project开源的一个分布式计算的统一接口。 fugue 0.9.2及之前版本存在代码问题漏洞，该漏洞源于FlaskRPCServer通过pickle反序列化实现远程代码执行。
