      "value": "The Keep Backup Daily plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the backup title alias (`val` parameter) in the `update_kbd_bkup_alias` AJAX action in all versions up to, and including, 2.1.2. This is due to insufficient input sanitization and output escaping. While `sanitize_text_field()` strips HTML tags on save, it does not encode double quotes. The backup titles are output in HTML attribute contexts without `esc_attr()`. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts via attribute injection that will execute whenever another administrator views the backup list page."

Esto se debe a una sanitización de entrada y un escape de salida insuficientes. Aunque 'sanitize_text_field()' elimina las etiquetas HTML al guardar, no codifica las comillas dobles. Los títulos de las copias de seguridad se muestran en contextos de atributos HTML sin 'esc_attr()'. Esto hace posible que atacantes autenticados, con acceso de nivel de Administrador y superior, inyecten scripts web arbitrarios a través de la inyección de atributos que se ejecutarán cada vez que otro administrador vea la página de la lista de copias de seguridad."
