This is due to insufficient input sanitization and output escaping in the Advanced_Search::content() render callback: the attribute value is filtered with wp_kses(), which strips disallowed HTML tags but does NOT escape HTML special characters such as double quotes in plain text, and the result is then concatenated directly into the data-viewmoretext HTML attribute without 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> wpxpo Post Grid Gutenberg Blocks – PostX</p> <p>The Ultimate Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;moreResultsText&#39; block attribute of the ultimate-post/advanced-search block in versions up to and including 5.0.31.
