    Summary: Captcha verification bypass in github.com/mojocn/base64Captcha

    Details: 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.
