FKIE_CVE-2026-3657

Vulnerability from fkie_nvd - Published: 2026-03-12 03:15 - Updated: 2026-03-12 21:07
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
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.

Si bien los valores de los par\u00e1metros se sanean con \u0027esc_sql()\u0027 y \u0027sanitize_text_field()\u0027, las claves de los par\u00e1metros se utilizan tal cual para construir la lista de columnas en la sentencia INSERT.
