CVE-2025-4208: Basixonline Nex-Forms

Medium severity, CVSS 6.3. EPSS: 0.4% chance of exploitation in the next 30 days.

The NEX-Forms – Ultimate Form Builder – Contact forms and much more plugin for WordPress is vulnerable to Limited Code Execution in all versions up to, and including, 8.9.1 via the get_table_records function. This is due to the unsanitized use of user-supplied input in call_user_func(). This makes it possible for authenticated attackers, with Custom-level access, to execute arbitrary PHP functions that meet specific constraints (static methods or global functions accepting a single array parameter).

Affected products

• Basixonline Nex-Forms: up to and including 8.9.2
