### 󠀁[Easily bypassed, vulnerable](https://wordpress.org/support/topic/easily-bypassed-vulnerable/)󠁿

This plugin does not really work to stop automated registrations, and here’s why:
Inside wm-simple-captcha/classes/wm_simple_captcha_front.php in the captcha_errors
method, which is supposed to do the validation of the code, the whole logic is wrapped
in a if(isset($_REQUEST['captcha_challenge_field'])){ block. What this means is 
that if the request does not contain the captcha challenge field then no errors 
are output and the captcha is not considered invalid at all, successfully letting
the registration through. Try it yourself, open the /wp-login.php?action=register
page, enter Developer Tools and delete the capthca input box. Viola! Do you really
think that automated registration scripts will actually submit all the form inputs?
Because they won’t. They’ll simply send a POST request to /wp-login.php?action=register
with the bare minimum username and email parameters and they’ll get through. And
they don’t. Thus, this plugin does absolutely nothing to stop spam registrations,
contains a captcha bypass vulnerability.
