CVE-2026-4059

Description

The ShopLentor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the woolentor_quickview_button shortcode's button_text attribute in all versions up to, and including, 3.3.5. This is due to insufficient input sanitization and missing output escaping on user-supplied shortcode attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
