The WPSyncSheets Lite For WPForms – WPForms Google Spreadsheet Addon plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wpsslwp_reset_settings() function in all versions up to, and including, 1.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to reset the plugin's settings.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
