PYSEC-2026-389
litellm vulnerable to remote code execution based on using eval unsafely
Quick fix
PYSEC-2026-389 — litellm: upgrade to the fixed version with the command below.
pip install --upgrade 'litellm>=1.40.16'Details
BerriAI/litellm version v1.35.8 contains a vulnerability where an attacker can achieve remote code execution. The vulnerability exists in the `add_deployment` function, which decodes and decrypts environment variables from base64 and assigns them to `os.environ`. An attacker can exploit this by sending a malicious payload to the `/config/update` endpoint, which is then processed and executed by the server when the `get_secret` function is triggered. This requires the server to use Google KMS and a database to store a model.
