SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. Prior to version 1.17.0, a path traversal vulnerability in chat endpoints allows an authenticated attacker to read and delete arbitrary files under their user data root (for example secrets.json and settings.json) by supplying avatar_url="..". This issue has been patched in version 1.17.0.
