CVE-2023-6141Public exploitNetwork attack vector

Stored XSS via unsanitized font selector

Published Jan 8, 2024 · Updated Jun 18, 2025

Stored XSS in G5Theme Essential Real Estate before 4.4.0 allows remote authenticated users to inject scripts through an AJAX request. The gsf_save_active_font action stores the font[0][selector] value without sufficient capability enforcement, input sanitization, or output escaping. Subscriber-level access is sufficient, and the injected script executes when a user visits an affected page.
