Squidex vulnerable to Server-Side Request Forgery (SSRF) via URL-based asset upload (/api/apps/{app}/assets)

Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, an SSRF vulnerability allows a user with asset upload permission to force the server to fetch arbitrary URLs, including localhost/private network targets, and persist the response as an asset. Version 7.23.0 contains a fix.
