Vulnerability from fkie_nvd - Published: 2026-03-21 04:17 - Updated: 2026-04-24 16:27
Severity ?
Summary
The WP Games Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [game] shortcode in all versions up to and including 0.1beta. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'width', 'height', 'src', 'title', 'description', 'game_url', 'main', and 'thumb', which are all directly concatenated into HTML output without any 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.

"value": "El plugin WP Games Embed para WordPress es vulnerable a cross-site scripting almacenado a trav\u00e9s del shortcode [game] en todas las versiones hasta la 0.1beta inclusive. Esto se debe a una sanitizaci\u00f3n de entrada y un escape de salida insuficientes en los atributos del shortcode proporcionados por el usuario, como \u0027width\u0027, \u0027height\u0027, \u0027src\u0027, \u0027title\u0027, \u0027description\u0027, \u0027game_url\u0027, \u0027main\u0027 y \u0027thumb\u0027, los cuales son todos concatenados directamente en la salida HTML sin ning\u00fan escape. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, inyecten scripts web arbitrarios en p\u00e1ginas que se ejecutar\u00e1n cada vez que un usuario acceda a una p\u00e1gina inyectada."
