CVE-2022-43305Network attack vector

Code execution via third-party dependency backdoor

Published Nov 7, 2022 · Updated May 5, 2025

Supply-chain compromise in d8s-python on PyPI allows attackers to execute code through the democritus-algorithms dependency. Public records identify that dependency as the backdoor's locus but do not disclose its malicious code, trigger, or executed payload. Exposure requires installation and execution of the compromised dependency, which runs with the affected Python process's privileges.
