AI-suggested

Upgrade transmute to version 1.3.0 or later, where this SSRF vulnerability is fixed. No other mitigation is indicated or required according to the available data.

Description

Transmute versions prior to 1.3.0 contain a Server-Side Request Forgery (SSRF) vulnerability in the URL import endpoint. This flaw allows authenticated or guest users to make the server perform HTTP requests to internal or cloud-local network resources. The vulnerability arises because the HTTP downloader follows redirects and does not validate target addresses. Downloaded content is stored and accessible, enabling full-read SSRF. The issue is fixed in version 1.3.0.
