Cloudflare Turnstile - Regex Test Issue

Hi!

Short and simply: The regex being used to test the input for the JS render parameter cData (using the regex /^[a-z0-9_-]{0,255}$/i - is not sufficient to enable base64 representations of data - specifically, you are missing the literal equals characters =.

var K = /^[a-z0-9_-]{0,255}$/i;
function B(e) {
    return K.test(e)
}
