CVE-2014-5204

Estado: ModificadaMedia (6.8)—

wp-includes/pluggable.php en WordPress anterior a 3.9.2 rechaza cadenas de caracteres de un sólo uso CSRF inválidos con diferencias de tiempo dependiendo de qué caracteres en la cadena de caracteres de un sólo uso sean incorrectos, lo que facilita a atacantes remotos evadir un mecanismo de protección CSRF a través de un ataque de fuerza bruta.
