CVE-2026-15665Network attack vector

Stored XSS via unescaped redirect shortcode attribute

Published Jul 24, 2026 · Updated Jul 24, 2026

Stored XSS in WPManageNinja Fluent Support 2.3.0 and earlier allows remote authenticated users to inject scripts via a redirect-to shortcode. AuthHandler copies the redirect-to shortcode attribute into the login form's hidden redirect field without sufficient sanitization or output escaping. Contributor-level access is required, and the stored payload executes only when a visitor uses specific browser access keys, allowing script execution within the visitor's WordPress origin.
