The flaw exists within the submit_form function, where insufficient validation of JSON field declarations allows for path manipulation. Attackers can bypass the ABSPATH security guard by using the dirname() function to strip trailing slashes, effectively traversing the filesystem. If an administrator has enabled the 'Delete files from server after form submissions' setting, an unauthenticated attacker can recursively delete arbitrary directories, including the entire WordPress installation. This vulnerability poses a severe risk to service availability and data integrity for any WordPress site utilizing this plugin with the specific administrative setting enabled.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a WordPress installation running a vulnerable version of the Super Forms plugin (\u0026lt;= 6.3.316).\u003c/li\u003e\n\u003cli\u003eAttacker verifies the plugin's 'Delete files from server after form submissions' setting is active, commonly found in plugin configurations.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious JSON payload targeting the submit_form function.\u003c/li\u003e\n\u003cli\u003eAttacker includes a directory path string designed to bypass the ABSPATH security guard via dirname() behavior.\u003c/li\u003e\n\u003cli\u003eAttacker sends an HTTP POST request to the plugin's submission endpoint containing the crafted JSON.\u003c/li\u003e\n\u003cli\u003eThe application parses the malicious JSON and fails to validate the directory path against the intended schema.\u003c/li\u003e\n\u003cli\u003eThe application executes the recursive deletion command on the provided target path.\u003c/li\u003e\n\u003cli\u003eFinal objective is achieved as the target directory (e.g., WordPress root) is deleted from the server.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation results in the recursive deletion of arbitrary directories on the host server.
