This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Although the AJAX action requires a per-item nonce, that nonce is publicly emitted in the page's <script class="gdrts-rating-data"> JSON block on every page rendering the rating item, making it obtainable by any unauthenticated visitor and therefore not an authentication barrier. ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
