text-generation-webui is an open-source web interface for running Large Language Models. Prior to 4.3, an unauthenticated path traversal vulnerability in load_preset() allows reading any .yaml file on the server filesystem. The parsed YAML key-value pairs (including passwords, API keys, connection strings) are returned in the API response. This vulnerability is fixed in 4.3.
