SCA: security update for litellm (GHSA-4xpc-pv4p-pm3w)

critical Tenable Cloud Security Plugin ID 443343

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. Prior to 1.84.0, a
 Host-header parsing flaw in the LiteLLM proxy could, under specific conditions, allow unauthenticated
 access to protected management routes. The auth layer derived the effective route from request.url.path in
 litellm/proxy/auth/auth_utils.py::get_request_route(), which Starlette reconstructs from the Host header.
 A crafted Host could therefore make the auth gate evaluate a different route from the one FastAPI
 dispatched. This vulnerability is fixed in 1.84.0. (CVE-2026-49468)

Solution

Update the litellm library and its related packages to version 1.84.0 or later.
