CVE-2026-3657

HIGHNVD 7.57.5—

7.5

The My Sticky Bar plugin for WordPress is vulnerable to SQL injection via the stickymenu_contact_lead_form AJAX action in all versions up to, and including, 2.8.6. This is due to the handler using attacker-controlled POST parameter names directly as SQL column identifiers in $wpdb->insert(). While parameter values are sanitized with esc_sql() and sanitize_text_field(), the parameter keys are used as-is to build the column list in the INSERT statement. This makes it possible for unauthenticated attackers to inject SQL via crafted parameter names, enabling blind time-based data extraction from the database.
