CVE-2026-5581 Details
Description
The Multi Uploader for Gravity Forms plugin for WordPress is vulnerable to unauthorized arbitrary media deletion in all versions up to, and including, 1.1.8. This is due to missing capability checks in the `plupload_ajax_delete_file()` function, which is registered via `wp_ajax_nopriv_gfmu_delete_file`. The nonce intended for CSRF protection is exposed on any public-facing page containing a multi-uploader form field via the `GFMU_options` JavaScript object. This makes it possible for unauthenticated attackers to permanently delete any WordPress media attachment by supplying its attachment ID, potentially leading to complete media library destruction.
A vulnerability exists in the Multi Uploader for Gravity Forms WordPress plugin, affecting all versions through 1.1.8. The issue arises from inadequate capability checks in the 'plupload_ajax_delete_file' function, which is accessible to unauthenticated users. This vulnerability allows for the unauthorized deletion of WordPress media attachments by exploiting a nonce intended for Cross-Site Request Forgery (CSRF) protection, which is publicly available on any page with a multi-uploader form field. As a result, an attacker could permanently remove media files, potentially leading to the complete destruction of the media library.
Users are advised to update the Multi Uploader for Gravity Forms plugin to version 1.1.9 or later.
