text-generation-webui is an open-source web interface for running Large Language Models.
Impact
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_template() allows reading files with .jinja, .jinja2, .yaml, or .yml extensions from anywhere on the server filesystem. For .jinja files the content is returned verbatim; for .yaml files a parsed key is extracted. This vulnerability is fixed in 4.3.
