CVE-2022-38884Network attack vector

Code execution via uncontrolled PyPI dependency

Published Sep 19, 2022 · Updated Aug 3, 2024

Dependency confusion in d8s-grammars 0.1.0 allows attackers to execute arbitrary code when the package is installed from PyPI. Its package metadata declares democritus-strings, a dependency name outside the maintainer's control, so pip retrieves and installs third-party code. Execution requires installation of the yanked 0.1.0 release and is bounded to the privileges of the Python environment running pip.
