Vulnerability Overview

The Display custom fields in the frontend – Post and User Profile Fields plugin for WordPress is vulnerable to Code Injection via the plugin's vg_display_data shortcode in all versions up to, and including, 1.2.1 due to insufficient input validation and restriction on access to that shortcode. This makes it possible for authenticated attackers with contributor-level and above permissions to call arbitrary functions and execute code.

Technical Analysis

REMEDIATION: Update to version 1.3.0, or a newer patched version --- IDENTIFIER: CWE-94 (Improper Control of Generation of Code ('Code Injection')) The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
