Description
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 /api/chats/import allows an authenticated attacker to write attacker-controlled files outside the intended chats directory by injecting traversal sequences into character_name. This issue has been patched in version 1.17.0.
