Vulnerability Title
Discourse moderators can access admin-only reports exposing private upload URLs
Source: CVE Program / CVE List V5
Vulnerability Description
Discourse is an open source discussion platform. In versions prior to 3.5.4, 2025.11.2, 2025.12.1, and 2026.1.0, moderators can access the `top_uploads` admin report which should be restricted to admins only. This report displays direct URLs to all uploaded files on the site, including sensitive content such as user data exports, admin backups, and other private attachments that moderators should not have access to. This issue is patched in versions 3.5.4, 2025.11.2, 2025.12.1, and 2026.1.0. There is no workaround. Limit moderator privileges to trusted users until the patch is applied.
