CVE-2023-0544Public exploitNetwork attack vector

Stored script execution via unescaped greeting text

Published May 8, 2023 · Updated May 5, 2025

Stored XSS in Itzoovim WP Login Box 2.0.2 and earlier allows remote authenticated users to execute scripts via admin settings. The Greeting Text setting stores unescaped script markup, which the enabled [wplb] shortcode renders in a visitor's page. Administrator privileges and disabled unfiltered_html, such as on WordPress multisite, are required; viewing the injected page triggers script execution.
