What happened
On 21 October 2026 an attacker published a tampered release of LiteLLM, a Python library for calling AI models, as version 1.107.0 on PyPI and under thev1.107.0, latest, main-latest and main-stable Docker tags. The package installed a credential stealer and a remote code loader that ran whenever any Python process started on the host. The PyPI package was live from 11:39 to 13:23 UTC and the Docker images until 14:20 UTC.
LiteLLM has asked anyone who installed that version during the window to treat the machine as compromised and rotate credentials.
