WM Simple Captcha

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 100% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   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.

   I went out of my way to review this plugin because: It does exactly what it says It is WAY more flexible out of the box than I would have imagined (colors, fonts, language, etc.) It is by far the best plugin I have downloaded in a long time
