Technical details
The plugin fails to sanitize Facebook comment content before rendering it via v-html in the admin preview component, and uses v-show rather than v-if, causing injected HTML and event handlers to be evaluated in the DOM even when hidden. An unauthenticated attacker with a Facebook account can post a malicious comment; when an administrator previews the feed, arbitrary JavaScript executes in their session. Combined with a missing URL validation flaw in the cff_install_addon AJAX handler, an injected script can trigger arbitrary plugin installation from attacker-controlled servers, resulting in remote code execution.
