      "value": "The StatCounter – Free Real Time Visitor Stats plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.1.1 This is due to insufficient output escaping on the post author's nickname in the statcounter_addToTags() function. The function is hooked to wp_head and fires on every single post page. It retrieves the post author's nickname via the_author_meta() and echoes it directly into a JavaScript double-quoted string context inside a <script> block without applying esc_js() or any equivalent JavaScript-context escaping. This makes it possible for authenticated attackers with Author-level access and above to inject arbitrary web scripts into pages that will execute whenever any user (including unauthenticated visitors) accesses a post authored by the attacker."

      "value": "El plugin StatCounter – Free Real Time Visitor Stats para WordPress es vulnerable a cross-site scripting almacenado en versiones hasta, e incluyendo, la 2.1.1. Esto se debe a un escape de salida insuficiente en el apodo del autor de la publicación en la función statcounter_addToTags(). La función está enganchada a wp_head y se activa en cada página de publicación individual. Recupera el apodo del autor de la publicación a través de the_author_meta() y lo imprime directamente en un contexto de cadena de JavaScript entre comillas dobles dentro de un bloque <script> sin aplicar esc_js() ni ningún escape equivalente de contexto de JavaScript. Esto hace posible que atacantes autenticados con acceso de nivel de Autor y superior inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que cualquier usuario (incluidos los visitantes no autenticados) acceda a una publicación escrita por el atacante."
