CVE-2026-34522 Details
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.
A path traversal vulnerability has been identified in SillyTavern versions prior to 1.17.0. The issue resides in the '/api/chats/import' endpoint, where authenticated attackers can inject traversal sequences into the 'character_name' parameter. This injection allows them to write files to locations outside the designated chats directory. The vulnerability arises because 'character_name' is used unsafely in the filename, passed into 'path.join()' without proper sanitization. Exploitation of this vulnerability could lead to unauthorized file creation in sensitive areas of the filesystem, potentially disrupting normal application operations or abusing disk space.
Users are advised to update SillyTavern to version 1.17.0 or later, where this vulnerability has been patched.
