CVE-2022-40808Network attack vector

Arbitrary code execution via unclaimed dependency

Published Sep 19, 2022 · Updated Aug 3, 2024

Dependency confusion in d8s-dates 0.1.0 allows attackers to execute arbitrary code through a malicious PyPI dependency. Its requirements file passes the unversioned democritus-hypothesis name to package resolution even though the maintainer no longer controlled that name, permitting a third-party distribution to satisfy it. Exposure requires installing d8s-dates 0.1.0 from PyPI; the public records do not disclose which package hook executes the dependency code.
