CVE-2026-5581
No known patch is available for this vulnerability.
The affected plugin has not been updated on WordPress.org since before this CVE was disclosed; the latest installable version is still vulnerable. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
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.
