This is due to insufficient input sanitization and output escaping when handling the Google Maps iframe custom field. The saveCustomFields() function in class-contact-list-custom-fields.php uses a regex to extract <iframe> tags from user input but does not validate or sanitize the iframe's attributes, allowing event handlers like 'onload' to be included. The extracted iframe HTML is stored via update_post_meta() and later rendered on the front-end in class-cl-public-card.php without any escaping or wp_kses filtering. 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."}, {"lang": "es", "value": "El plugin Contact List para WordPress es vulnerable a cross-site scripting almacenado a trav\u00e9s del par\u00e1metro '_cl_map_iframe' en todas las versiones hasta la 3.0.18, inclusive.
