CVE-2026-1922

The The Events Calendar Shortcode & Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `ecs-list-events` shortcode `message` attribute in all versions up to, and including, 3.1.2 due to insufficient input sanitization and output escaping on user supplied attributes. 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 The Events Calendar Shortcode & Block para WordPress es vulnerable a cross-site scripting almacenado a través del atributo 'message' del shortcode 'ecs-list-events' del plugin en todas las versiones hasta la 3.1.2, e incluyendo, debido a una sanitización de entrada y escape de salida insuficientes en los atributos proporcionados por el usuario.
