CVE-2020-36702Public exploitNetwork attack vector

Subscriber-level settings changes via leaked AJAX nonce

Published Jun 7, 2023 · Updated Apr 8, 2026

Missing authorization in Spectra Legacy 1.14.7 and earlier allows remote authenticated users to change plugin settings through AJAX. Six handlers in classes/class-uagb-admin.php omit capability checks and accept the same uagb-block-nonce, which the plugin exposes when a logged-in user posts page=uag. Subscriber-level access is sufficient to activate or deactivate blocks, toggle beta updates, and change file-generation behavior.
