CVE-2022-42043Network attack vector

Code execution via hijacked package dependency

Published Oct 11, 2022 · Updated May 19, 2025

Code-execution backdoor in d8s-xml 0.1.0 allows attackers to execute code by installing its democritus-html dependency. The release metadata declares a dependency name no longer controlled by the maintainer, allowing PyPI to resolve a third-party democritus-html package. Exploitation requires installation of d8s-xml 0.1.0 and dependency resolution from PyPI; public records do not disclose the payload or execution trigger.
