Technical details
The plugin's bpxp_image_field_update_on_user_activation() function calls unlink() on a path constructed from user-supplied signup metadata (the 'field_N_hidden' parameter) without realpath() resolution, directory containment checks, or file-type validation. An unauthenticated attacker can submit a zero-byte file during registration; when the pending signup is activated, this malicious path is resolved against the document root, enabling arbitrary file deletion and potential RCE.
Affected products
