SCA: security update for sillytavern (GHSA-gxx6-h3g6-vwjh)
critical Tenable Self-Hosted Container Security Plugin ID 441784
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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, SillyTavern
accepts Remote-User (Authelia) and X-Authentik-Username (Authentik) HTTP headers to automatically log in
users when SSO is configured. There is no validation that these headers originate from a trusted reverse
proxy. Any network client that can reach the SillyTavern port directly can inject these headers and
authenticate as any user, including administrators, without a password. This vulnerability is exploitable
only when sso.autheliaAuth: true or sso.authentikAuth: true is set in config.yaml (both default to false).
This vulnerability is fixed in 1.18.0. (CVE-2026-44649)
Solution
Update the sillytavern library and its related packages to version 1.18.0 or later.See Also
