CVE-2026-111966 · Severity: info · Published 2026-10-23

User Profile Builder is a WordPress plugin that manages user registration and profile forms. The plugin fails to sanitize a shortcode attribute before displaying it in redirect messages, allowing authenticated contributors to inject malicious code that executes when higher-privileged users submit forms. This could lead to account compromise, credential theft, or administrator impersonation.

## Technical details

The plugin does not sanitize or escape the redirect_url shortcode attribute before outputting it in a redirect message, resulting in a stored cross-site scripting (XSS) vulnerability. An attacker with contributor role can inject JavaScript through the shortcode, which executes in the browser of higher-privileged users who interact with the affected form. The attack requires form submission by a victim to trigger payload execution.
