Unauthenticated code execution via user-selected function calls
Published Aug 6, 2025 · Updated Apr 8, 2026
Remote code execution in eight WordPress plugins using emd-form-builder-lite allows remote attackers to call parameterless PHP functions. The emd_form_builder_lite_pagenum function accepts unvalidated request input and invokes that value as a PHP function name instead of restricting it to expected pagination callbacks. No authentication or user interaction is required, but the call cannot supply function parameters, limiting execution to callable functions that are useful without arguments.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
