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 the static file route handler allows any unauthenticated user to determine whether files exist anywhere on the server's filesystem. by sending percent-encoded "../" sequences (%2E%2E%2F) in requests to static file routes, an attacker can check for the existence of files. This issue has been patched in version 1.17.0.
