Subscriber-level code execution via unrestricted function call
Published May 15, 2025 · Updated Apr 8, 2026
Code injection in UiPress Lite 3.5.07 and earlier allows remote authenticated users to execute arbitrary PHP code through form submissions. The uip_process_form_input() handler reads userFunction and formData from POST data, verifies only an AJAX nonce, and invokes the named PHP function with attacker-controlled data without a capability check or callable allowlist. Subscriber-level access and a valid nonce suffice, enabling arbitrary code execution and complete compromise of the WordPress site.

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.
