The xorg-renderproto package published on PyPI was found to contain malicious code. This appears to be a typosquatting or name-confusion attack, as the legitimate xorg-renderproto is an X.Org protocol specification package, not a Python package.\n\nThe malicious package was identified and cataloged by the OpenSSF's malicious packages project (reference MAL-2025-41800). The incident was disclosed via a GitHub Security Advisory (GHSA-x66f-7x29-8cj8) on July 21, 2026.\n\nAny system that installed this malicious package would have been compromised by the embedded malicious code.
