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.
