Details
As written in the advisory (Markdown source, shown as plain text).
Froala WYSIWYG HTML Editor is a lightweight WYSIWYG HTML Editor written in JavaScript that enables rich text editing capabilities for web applications. A DOM-based cross-site scripting (XSS) vulnerability exists in versions before 3.2.3 because HTML code in the editor is not correctly sanitized when inserted into the DOM. This allows an attacker that can control the editor content to execute arbitrary JavaScript in the context of the victim’s session.
