CVE-2026-4090 - Inquiry Cart Plugin

CVE-2026-4090

The Inquiry Cart plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.4.2. This is due to missing nonce verification in the rd_ic_settings_page function when processing settings form submissions. This makes it possible for unauthenticated attackers to update the plugin's settings, including injecting malicious scripts that will be stored and executed in the admin area, via a forged request granted they can trick an administrator into performing an action such as clicking on a link.
