CVE-2026-11356

Description

The Ivory Search – WordPress Search Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'menu_title' and 'menu_magnifier_color' Settings in all versions up to, and including, 5.5.15 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
