CVE-2022-41380Network attack vector

Code execution via malicious transitive dependency

Published Oct 11, 2022 · Updated May 20, 2025

Malicious dependency inclusion in d8s-yaml 0.1.0 allows attackers to execute code when the affected release is installed from PyPI. Its requirements.txt unconditionally names democritus-file-system, so pip resolves and installs that third-party package with d8s-yaml. An attacker able to publish the dependency can place arbitrary code on systems that install the affected release; public sources do not identify a specific executed file or hook.
