Overview
apostrophe is a content management system (CMS) for Node.js. It supports in-context editing, schema-driven content types, flexible widgets and a great deal more. This module contains everything necessary to build a website with ApostropheCMS.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the sanitize image import path in the @apostrophecms/rich-text-widget module. An attacker can make the server fetch arbitrary image URLs by supplying rich text HTML with an <img> tag and a crafted src value during HTML import. This lets the attacker probe internal hosts and retrieve image content from reachable internal or external endpoints, exposing network resources and data to the user running the import.
