CVE-2026-44650 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 1.18.0, POST /api/extensions/delete endpoint accepts extensionName: "." which bypasses sanitize-filename validation, causing the entire user extensions directory to be recursively deleted. No authentication is required in the default configuration. This vulnerability is fixed in 1.18.0.
A critical path traversal vulnerability has been identified in SillyTavern versions through 1.17.0. The issue arises in the POST /api/extensions/delete endpoint, where the extensionName parameter can be manipulated to bypass filename validation. This allows for the entire user extensions directory to be recursively deleted. The vulnerability does not require authentication in the default configuration.
Users can update to SillyTavern version 1.18.0 or later, where this vulnerability has been fixed.
