This is due to insufficient input sanitization and output escaping in the post_thumbnail() method in helpers/shortcode.php, which concatenates the user-controlled $link shortcode attribute directly into an href attribute without esc_url() or esc_attr(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.</p> <p><strong>Affected:</strong> contrid Newsletters</p> <p>The Newsletters Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;link&#39; attribute of the post_thumbnail (and newsletters_post_thumbnail) shortcodes in versions up to and including 4.15.
