Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, the "RestoreController.PostRestoreJob" endpoint allows an administrator to supply an arbitrary URL for downloading backup archives. This URL is fetched using the "Backup" "HttpClient" without any SSRF protection. A malicious or compromised admin can use this endpoint to probe internal network services, access cloud metadata endpoints, or perform internal reconnaissance. The vulnerability is authenticated (Admin-only) but highly impactful, allowing potential access to sensitive internal resources. Version 7.23.0 contains a fix.
