summary: Captcha verification bypass in github.com/mojocn/base64Captcha
description: |-
    When using the default implementation of Verify to check a Captcha, verification
    can be bypassed.

    For example, if the first parameter is a non-existent id, the second parameter
    is an empty string, and the third parameter is true, the function will always
    consider the Captcha to be correct.
