Common questions
How do I fix CVE-2022-40897?
Published advisories record a fix for 467 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.
Is CVE-2022-40897 being actively exploited?
Not that we know of. CVE-2022-40897 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 2.6% is the estimated probability that it will be exploited in the next 30 days. That is higher than 85% of all scored CVEs.
How severe is CVE-2022-40897?
CVE-2022-40897 has a CVSS v3 base score of 5.9, rated medium. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.
What does CVE-2022-40897 affect?
Published advisories record a fix for python-setuptools-wheel (Amazon), python2-setuptools (Amazon), python3-setuptools (Amazon), python3-setuptools-wheel (Amazon), and 463 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
