The Unlimited Elements for Elementor plugin for WordPress is vulnerable to SQL Injection via the 'data[filter_search]' parameter in the get_cat_addons AJAX action in versions up to and including 2.0.7. This is due to insufficient input sanitization and the use of deprecated escaping functions combined with direct string concatenation in SQL query construction. The vulnerability is exacerbated because the normalizeAjaxInputData() function calls stripslashes() on all user input, removing the protection provided by WordPress's wp_magic_quotes() function. Subsequently, the filter_search parameter is escaped using the deprecated wpdb->_escape() function and then directly concatenated into a LIKE clause without using prepared statements. This makes it possible for authenticated attackers, with Contributor-level access and above (who can obtain a valid nonce through the Elementor editor), to inject arbitrary SQL commands and extract sensitive information from the database.

Multiple plugins and/or themes for WordPress are vulnerable to Reflected Cross-Site Scripting via the url parameter in various versions due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Unlimited Elements for Elementor plugin for WordPress is vulnerable to Arbitrary File Read via the Repeater JSON/CSV URL parameter in versions up to, and including, 2.0.6. This is due to insufficient path traversal sanitization in the URLtoRelative() and urlToPath() functions, combined with the ability to enable debug output in widget settings. The URLtoRelative() function only performs a simple string replacement to remove the site's base URL without sanitizing path traversal sequences (../), and the cleanPath() function only normalizes directory separators without removing traversal components. This allows an attacker to provide a URL like http://site.com/../../../../etc/passwd which, after URLtoRelative() strips the domain, results in /../../../../etc/passwd being concatenated with the base path and ultimately resolved to /etc/passwd. This makes it possible for authenticated attackers with Author-level access and above to read arbitrary local files from the WordPress host, including sensitive files such as wp-config.

The Unlimited Elements for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the form entry fields in all versions up to, and including, 2.0.5.

The Doubly – Cross Domain Copy Paste for WordPress plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.0.46 via deserialization of untrusted input from the content.txt file within uploaded ZIP archives. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to execute arbitrary code, delete files, retrieve sensitive data, or perform other actions depending on the available gadgets. This is only exploitable by subscribers, when administrators have explicitly enabled that access.

The Unlimited Elements For Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 2.0 due to insufficient input sanitization and output escaping.
