DESCRIPTION:
neworder has discovered a vulnerability in the is_human() plugin for
WordPress, which can be exploited by malicious people to compromise a
vulnerable system.

Input passed to the "type" parameter in engine.php (when e.g.
"action" is set to "log-reset") is not properly verified before being
used in an "eval()" function and can be exploited to inject and
execute arbitrary PHP code.

The vulnerability is confirmed in version 1.4.2. Other versions may
also be affected.

SOLUTION:
Use a different product.
