- CVE-2025-11977, 10 Jul 2026
- The Happyforms - Form Builder for WordPress: Drag & Drop Contact Forms, Surveys, Payments & Multipurpose Forms plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.26.12 via the happyforms_get_form_partial() function. This makes it possible for authenticated attackers, with Administrator-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. CVE record

- CVE-2023-0096, 6 Feb 2023

What to do if you run Happyforms
If you run Happyforms, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
