The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the deleteentryfiles() function in all versions up to, and including, 1.7.3. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.7.3 via the use of fileexists() in the deleteentryfiles() function without restriction on the path provided. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
