CVE-2023-44467: langchain_experimental vulnerable to arbitrary code execution via PALChain in the python exec method

Severity: Critical

CVSS Score: 9.8

langchain_experimental (aka LangChain Experimental) in LangChain before 0.0.306 allows an attacker to bypass the CVE-2023-36258 fix and execute arbitrary code via __import__ in Python code, which is not prohibited by pal_chain/base.py.
