Description

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.
