Taint es una extensión que sirve para detectar código XSS (strings
|
|
corrompidos, «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 <varname>$_GET</varname>, <varname>$_POST</varname>
|
|
o <varname>$_COOKIE</varname>) a alguna función.
