HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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`.
