NewCVE-2026-41129 (opens in a new tab)How to fix?
Upgrade craftcms/cms to version 4.17.9, 5.9.15 or higher.
Overview
craftcms/cms is a content management system.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the asset upload mutations process. An attacker can interact with internal services by supplying specially crafted URLs using unsupported schemes, such as gopher, which bypasses standard hostname validation and allows raw TCP commands to be sent to internal endpoints. This is only exploitable if the GraphQL schema grants permissions to edit and create assets in a volume.
