Upgrade litellm to version 1.80.11 or higher.
Overview
litellm is a Library to easily interface with LLM API providers
Affected versions of this package are vulnerable to Information Exposure due to improper masking of raw request headers in the pre_call method of litellm/litellm_core_utils/litellm_logging.py. An attacker can obtain exposed API keys by triggering failures on the /health endpoint, which causes unmasked Authorization headers containing credentials to be included in the error response via raw_request_typed_dict.
Note: Successful exploitation of this vulnerability requires the attacker to have access to the network traffic.
