CVE-2026-0833

The Team Section Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's block in all versions up to, and including, 2.0.0 due to insufficient input sanitization and output escaping on user-supplied social network link URLs. 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.

Summary		(es) El plugin Team Section Block para WordPress es vulnerable a cross-site scripting almacenado a través del bloque del plugin en todas las versiones hasta la 2.0.0, inclusive, debido a una sanitización de entrada y un escape de salida insuficientes en las URL de enlaces de redes sociales proporcionadas por el usuario. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.
