SCA: security update for sillytavern (GHSA-wm7j-m6jm-8797)

medium Tenable Self-Hosted Container Security Plugin ID 439640

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 version 1.17.0, in
src/endpoints/search.js, the hostname is checked against /^\d+\.\d+\.\d+\.\d+$/. This only matches literal
dotted-quad IPv4 (e.g. 127.0.0.1, 10.0.0.1). It does not catch: localhost (hostname, not dotted-quad),
[::1] (IPv6 loopback), and DNS names resolving to internal addresses (e.g. localtest.me -> 127.0.0.1). A
separate port check (urlObj.port !== '') limits exploitation to services on default ports (80/443), making
this lower severity than a fully unrestricted SSRF. This issue has been patched in version 1.17.0.
(CVE-2026-34526)

Solution

Update the sillytavern library and its related packages to version 1.17.0 or later.
