 "title": "GSheetConnector For Ninja Forms <= 2.0.2 - Missing Authorization to Authenticated (Subscriber+) Google Sheets Access Code Update",
 "description": "The GSheetConnector For Ninja Forms plugin for WordPress is vulnerable to unauthorized modification of data via the verify_njforms_gs_integation AJAX action in all versions up to, and including, 2.0.2, due to a missing capability check. The handler only verifies a nonce, and Subscriber-level users can obtain that nonce from the plugin's settings page. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the site's stored Google OAuth access code and re-run authorization, replacing the site's Google Sheets connection with one tied to an attacker-controlled Google account and disrupting the sync of form submissions.",
