CVE-2022-40897: pypa/setuptools vulnerable to Regular Expression Denial of Service (ReDoS)
(updated )
Python Packaging Authority (PyPA)’s setuptools is a library designed to facilitate packaging Python projects. Setuptools version 65.5.0 and earlier could allow remote attackers to cause a denial of service by fetching malicious HTML from a PyPI package or custom PackageIndex page due to a vulnerable Regular Expression in package_index. This has been patched in version 65.5.1.
