Subscriber-level license option modification via unchecked AJAX handler
Published May 5, 2021 · Updated Aug 3, 2024
Incorrect authorization in Bitorbit WPBakery Page Builder Clipboard before 4.5.8 allows remote authenticated users to alter license data. The vc_clipboard_activate AJAX handler accepts attacker-supplied email and license_key parameters and writes them without verifying the caller's capabilities. A WordPress subscriber session is sufficient; exploitation changes only the stored license email and key, with no reported code execution or broader administrative control.
