CVE-2026-6447 | Call for Price for WooCommerce <= 4.2.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'Call for Price' Label Settings

The Call for Price for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.2.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
