Taint es una extensión que sirve para detectar código XSS (cadenas de caracteres
|
|
corrompidas, «tainted»).
|
|
También se puede utilizar para localizar vulnerabilidades a inyecciones SQL, inyecciones
|
|
«shell», etc.

|
|
Si taint está habilitada, advertirá de si se ha proporcionado una cadena corrompida
|
|
(que venga de $_GET, $_POST o $_COOKIE) a alguna función.
