CVE-2026-8677

Estado: AplazadaMedia (6.4)—

The Prime Elementor Addons – Lightweight Elementor Widgets for Faster Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Widget HTML Tag Settings in all versions up to, and including, 1.3.3 due to insufficient input sanitization and output escaping. 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. The exploit succeeds even for users without the unfiltered_html capability because the payload (e.g., 'img src=x onerror=alert(document.domain)') contains no HTML angle brackets and therefore passes through Elementor's wp_kses_post() filter unchanged at save time.

Esto permite a atacantes autenticados, con acceso de nivel de colaborador y superior, inyectar scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. El exploit tiene éxito incluso para usuarios sin la capacidad unfiltered_html porque la carga útil (p. ej., 'img src=x onerror=alert(document.domain)') no contiene corchetes angulares HTML y, por lo tanto, pasa a través del filtro wp_kses_post() de Elementor sin cambios al momento de guardar."
