- CVE-2026-82901, 26 Sep 2026
- The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Arbitrary File Upload due to insufficient file type validation in the 'uacf7_wpcf7_mail_components' function in all versions up to, and including, 3.5.50. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: This is only exploitable when the plugin's PDF Generator module is enabled, which is disabled by default. CVE record
- CVE-2026-84750, 19 Sep 2026
- The Ultra Addons for Contact Form 7 WordPress plugin before 3.5.51 does not validate the type or extension of files uploaded through one of its form fields, and stores them at a predictable public path with the attacker-chosen extension intact, allowing unauthenticated users to upload arbitrary files. The PHP handler shipped by default with the Debian and Ubuntu Apache packages maps .phar to PHP alongside .php and .phtml, so on that stack the uploaded file is executed and the issue leads to Remote Code Execution and full site takeover. Where the host routes only .php to the PHP handler, the same file is instead served from the site's own origin with its script intact, leading to Stored Cross-Site Scripting. CVE record
- CVE-2026-12801, 7 Aug 2026
- The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Range Slider 'data-label' and 'data-separator' attributes in all versions up to, and including, 3.5.43 due to insufficient input sanitization and output escaping. 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. CVE record
- CVE-2025-14356, 12 Dec 2025
- The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'uacf7_get_generated_pdf' function in all versions up to, and including, 3.5.33. This makes it possible for authenticated attackers, with Subscriber-level access and above, to generate and get form submission PDF, when the "PDF Generator" and the "Database" addons are enabled (disabled by default). CVE record
- CVE-2025-6756, 1 Jul 2025
- The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's UACF7_CUSTOM_FIELDS shortcode in all versions up to, and including, 3.5.21 due to insufficient input sanitization and output escaping on user supplied attributes. 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. CVE record
- CVE-2025-6212, 26 Jun 2025
- The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Database module in versions 3.5.11 to 3.5.19 due to insufficient input sanitization and output escaping. The unfiltered field names are stored alongside the sanitized values. Later, the admin-side AJAX endpoint ajax_get_table_data() returns those raw names as JSON column headers, and the client-side DataTables renderer injects them directly into the DOM without any HTML encoding. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2025-6220, 18 Jun 2025
- The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'save_options' function in all versions up to, and including, 3.5.12. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE record
- CVE-2023-2802, 14 Aug 2023
- The Ultimate Addons for Contact Form 7 WordPress plugin before 3.1.29 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup) CVE record
- CVE-2023-2803, 14 Aug 2023
- The Ultimate Addons for Contact Form 7 WordPress plugin before 3.1.29 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin. CVE record
- CVE-2023-1615, 9 Jun 2023
- The Ultimate Addons for Contact Form 7 plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in versions up to, and including, 3.1.23. This makes it possible for authenticated attackers of any authorization level to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. CVE record
