## Technical details

A path traversal vulnerability exists in the `/api/chats/export` and `/api/chats/delete` endpoints of SillyTavern. The root cause is an insufficient input validator in `src/middleware/validateFileName.js` that fails to block directory traversal sequences (e.g., '..') in the `avatar_url` parameter. By supplying a crafted `avatar_url` value, an authenticated attacker can escape the intended 'chats' directory to access the user data root. This allows for the unauthorized reading or deletion of sensitive files like `secrets.json` and `settings.json`. The issue is resolved in version 1.17.0 by improving path validation.
