The GSheetConnector For Gravity Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions less than, or equal to, 1.3.23. This is due to missing or incorrect nonce validation on the activateplugin and deactivateplugin functions. This makes it possible for attackers to trick authenticated administrators into activating or deactivating specified plugins via a forged request, such as clicking on a malicious link or visiting a compromised page.
The GSheetConnector For Gravity Forms plugin for WordPress is vulnerable to authorization bypass in versions less than, or equal to, 1.3.27. This is due to a missing capability check on the 'installplugin' function. This makes it possible for authenticated attackers, with subscriber-level access and above to install plugins on the target site and potentially achieve arbitrary code execution on the server under certain conditions.
