PYSEC-2026-3987

Published Sep 23, 2026·Last modified Sep 23, 2026
Affected Components(1)
PyPI logomemoryos
2.0.34
Description

An attacker with write access to the GitHub repository pushed malicious commits and tagged v2.0.34, and the project's own GitHub Actions release workflow built and uploaded 2.0.34 to PyPI. Importing the package runs memos/_stage0.py, which launches a bundled sckit binary that collects credentials (.pypirc, .npmrc, .git-credentials, SSH keys, token-like environment variables) and sends them to *.skyleen[.]fr.

Remove 2.0.34 and rotate any credentials reachable from affected machines.
