Echo: litellm: security update to 1.83.7

high Tenable Cloud Security Plugin ID 462653

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. From version 1.80.5
to before version 1.83.7, the POST /prompts/test endpoint accepted user-supplied prompt templates and
rendered them without sandboxing. A crafted template could run arbitrary code inside the LiteLLM Proxy
process. The endpoint only checks that the caller presents a valid proxy API key, so any authenticated
user could reach it. Depending on how the proxy is deployed, this could expose secrets in the process
environment (such as provider API keys or database credentials) and allow commands to be run on the host.
This issue has been patched in version 1.83.7. (CVE-2026-42203)

Solution

Update the litellm library and its related packages to version 1.83.7 or later.
