CVE-2021-24447Public exploitNetwork attack vector

Authenticated local file inclusion via unvalidated tab

Published Jul 19, 2021 · Updated Aug 3, 2024

Local file inclusion in SilkyPress WP Image Zoom before 1.47 allows remote authenticated users to include local files via the tab parameter. The admin settings page passes tab directly to include_once() without validating or restricting the requested path. Access to the WordPress admin dashboard is required, and the demonstrated result is an include_once() error that exposes server path information.
