Details

The WP Duplicate plugin for WordPress is vulnerable to Missing Authorization leading to Arbitrary File Upload in all versions up to and including 1.1.8. This is due to a missing capability check on the process_add_site() AJAX action combined with path traversal in the file upload functionality. This makes it possible for authenticated (subscriber-level) attackers to set the internal prod_key_random_id option, which can then be used by an unauthenticated attacker to bypass authentication checks and write arbitrary files to the server via the handle_upload_single_big_file() function, ultimately leading to remote code execution.

Severity ?
9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
