CVE-2026-53948: CWE-434: Unrestricted Upload of File with Dangerous Type in TryGhost GhostCVE-2026-53948 0 Ghost is a Node.js content management system. From 6.19.4 until 6.21.1, insufficient validation of the client-supplied Content-Type on Ghost's Admin API file upload endpoint allowed uploaded files to be served from the site with an attacker-chosen content type on S3/GCS storage backends. On installations that serve uploaded files from the same origin as the site, this could have been used to facilitate stored cross-site scripting against site visitors or staff. This vulnerability is fixed in 6.21.1. Join the discussion | CVE Database V5 | 06/24/2026, 18:06:30 UTC Added: 06/24/2026, 18:35:51 UTC |
