  • 0.0.52langchain-experimental, PyPIOSVpip install "langchain-experimental>=0.0.52"

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

langchain_experimental (aka LangChain Experimental) before 0.0.52, part of LangChain before 0.1.8, allows an attacker to bypass the CVE-2023-44467 fix and execute arbitrary code via the __import__, __subclasses__, __builtins__, __globals__, __getattribute__, __bases__, __mro__, or __base__ attribute in Python code. These are not prohibited by pal_chain/base.py.
