The CKEditor5 Youtube module enhances content creation in Drupal by seamlessly integrating YouTube video embedding into the CKEditor 5 text editor. The module doesn't sufficiently validate iframe sources under the scenario where a user embeds a video using the CKEditor YouTube integration leading to a Cross-site Scripting (XSS) vulnerabiity. This vulnerability is mitigated by the fact that an attacker must have a role with necessary permissions to use CKEditor Youtube embed button.
