DescriptionCVE.org

The NEX-Forms - Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the deactivate_license() function in all versions up to, and including, 9.1.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to to deactivate the plugin license.

AnalysisAI

The NEX-Forms Ultimate Forms Plugin for WordPress contains a missing capability check vulnerability in the deactivate_license() function, allowing authenticated attackers with Subscriber-level privileges to deactivate the plugin license without proper authorization. This authorization bypass affects all versions up to and including 9.1.9 and has a CVSS score of 4.3 (Low severity), indicating limited direct impact but meaningful privilege escalation concerns for multi-user WordPress installations.

Technical ContextAI

The vulnerability is rooted in CWE-862 (Missing Authorization), a common flaw in WordPress plugin development where capability checks are not properly enforced before executing sensitive functions. The affected product is the NEX-Forms Ultimate Forms Plugin (CPE: cpe:2.3:a:webnexus:nex-forms), a widely deployed WordPress plugin for form creation and management. The deactivate_license() function should restrict execution to administrators or users with explicit license management capabilities, but lacks these checks entirely. This allows any authenticated user—including those with minimal Subscriber-level access—to interact with licensing functionality that should be reserved for higher-privileged roles. The vulnerability represents a failure in WordPress plugin security best practices, specifically the omission of the current_user_can() capability check that should gate the license deactivation logic.

RemediationAI

Immediately upgrade the NEX-Forms Ultimate Forms Plugin to the patched version released after 9.1.9. Visit the official WordPress plugin repository or the vendor's website to download and install the latest version, which includes the missing capability check in the deactivate_license() function. As an interim mitigation, WordPress administrators should restrict Subscriber-level role permissions by reviewing user accounts and reducing unnecessary Subscriber accounts, limiting access to trusted administrators only via the WordPress admin panel. Additionally, implement rate limiting and IP-based access controls on the WordPress admin login endpoint using plugins such as Wordfence or by configuring your web server. Monitor plugin license status regularly and enable email notifications for license-related changes if the plugin provides such functionality.
