Database for Contact Form 7, WPforms, Elementor forms <= 1.5.1 - Unauthenticated Arbitrary File Copy/Upload via Elementor Pro Form Upload Field 'raw_value'

Description

The Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is vulnerable to Arbitrary File Copy via the create_entry_el() function in versions up to, and including, 1.5.1. The function reads raw_value from Elementor Pro's Form_Record object for upload-type fields and passes it directly to PHP's copy() without validating that the value corresponds to a legitimately uploaded file — when no file is present in $_FILES, raw_value reflects the attacker-controlled POST string. copy() accepts both local filesystem paths and URL sources, so the attacker can target any file readable by the PHP process or supply an attacker-controlled remote URL. Elementor Pro is a prerequisite for triggering the code path (it owns the elementor_pro/forms/new_record hook and populates the Form_Record object), but the bug itself is entirely in Contact Form Entries' handler. This could allow unauthenticated attackers to disclose arbitrary files on the affected site's server. The file is copied to a directory unknown to the attacker; the hashed directory name provides defense-in-depth but is generated from non-cryptographic sources (uniqid() + rand()) and should not be relied upon as the primary mitigation.
