FKIE_CVE-2026-8677
Vulnerability from fkie_nvd - Published: 2026-06-09 09:16 - Updated: 2026-07-23 08:10
Severity
Summary
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.

"value": "El plugin Prime Elementor Addons - Lightweight Elementor Widgets for Faster Pages para WordPress es vulnerable a cross-site scripting almacenado a trav\u00e9s de la configuraci\u00f3n de etiquetas HTML de widgets en todas las versiones hasta la 1.3.3, inclusive, debido a una sanitizaci\u00f3n de entrada y un escape de salida insuficientes. Esto permite a atacantes autenticados, con acceso de nivel de colaborador y superior, inyectar scripts web arbitrarios en p\u00e1ginas que se ejecutar\u00e1n cada vez que un usuario acceda a una p\u00e1gina inyectada. El exploit tiene \u00e9xito incluso para usuarios sin la capacidad unfiltered_html porque la carga \u00fatil (p. ej., \u0027img src=x onerror=alert(document.domain)\u0027) no contiene corchetes angulares HTML y, por lo tanto, pasa a trav\u00e9s del filtro wp_kses_post() de Elementor sin cambios al momento de guardar."
