The WYSWYG editor QuillJS is subject to potential XSS attach in case the attacker manages to modify the HTML before being uploaded to the server. The attacker is able to change e.g. to <svg onload=alert('XSS')> if they know how to craft these requests themselves.
If an attacker can infer the slug or URL of an unpublished or private resource, and this resource can be embedded (such as a Participatory Process, an Assembly, a Proposal, a Result, etc), then some data of this resource could be accessed.
The pagination feature used in searches and filters is subject to potential XSS attack through a malformed URL using the GET parameter per_page.
