      "value": "The jQuery Hover Footnotes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Footnote Qualifier (\u0027{{...}}\u0027 Syntax) in all versions up to, and including, 1.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The attribute-breakout payload (e.g., a double-quote followed by an event handler) contains no angle brackets and therefore bypasses WordPress core\u0027s wp_kses_post() filtering, which only strips disallowed HTML tags rather than sanitizing attribute contexts."

Esto hace posible que atacantes autenticados, con acceso de nivel de autor y superior, inyecten scripts web arbitrarios en p\u00e1ginas que se ejecutar\u00e1n cada vez que un usuario acceda a una p\u00e1gina inyectada. La carga \u00fatil de ruptura de atributo (por ejemplo, una comilla doble seguida de un gestor de eventos) no contiene corchetes angulares y, por lo tanto, omite el filtrado wp_kses_post() del n\u00facleo de WordPress, que solo elimina las etiquetas HTML no permitidas en lugar de sanitizar los contextos de atributos."
