Date: September 13th 2021

Hello everyone,

v11.15.1 has been released!

Download and install:


This release includes a few bug fixes dealing with potential security issues. The biggest one is the reCAPTCHA v2 problem - it’s very easy to circumvent its protection completely, so if you’re relying on reCAPTCHA v2, upgrade.

Changelog (and below):



This is a bugfix release, with changes to close up some potential security holes. It's an update we'd suggest for everyone. Most especially for people who are relying on Google reCAPTCHA v2 to protect their subscription forms. We've found that there is a way to circumvent the reCAPTCHA rendering it ineffective. There was also a bug found in the reCAPTHA v3 implementation, so we don't suggest simply switching to v3. More informaton can be found in these two issues:




Creating a new list can be done via a GET request


reCAPTCHA v3 check has strangely derefrenced variable in code, likely to cause issues.


Logging into the List Control Panel accepts a GET request


Dada Mail accepts GET requests to, "Forward to a Friend" form


Dada Mail accepts "subscribe" requests via GET


Attempting to send to a blank email address during a mass mailing will stall out the mass mailing (SMTP)


Google Recaptcha v2 check will return valid if problem with API call happens
