Recaptcha V2 just spins

[autohpn]

Issue description I have a problem with recaptcha v2. It has stopped working without having changed anything. When checking, it only rotates and does not verify.

Environment

• OS name and version: APACHE
• PHP version: 5.3.29
• Web server name and version: Linux 2.6.32-642.1.1.el6.x86_64
• google/recaptcha version: V2
• Browser name and version: ALL

This should be conflict with mootools: https://stackoverflow.com/questions/77473778/google-recaptcha-keeps-on-loading

https://stackoverflow.com/questions/77454968/joomla-recaptcha-issues

Compatability bind, that could have worked earlier (https://gist.github.com/sleemanj/f076ed2c0b887ab08074b55dad2fd636 https://github.com/google/recaptcha/issues/374#issuecomment-729881795) also stop working.

Thanks for your answer!

how can i solve this????? I don't found the solution :-(

[dimov-cz]

What version of Mootools do you use? 1.6.0 resolves some Array.from related issues.

[stdex]

I can confirm problem on mootools 1.4.2

[autohpn]

the problem happens with both 1.4.2 and 1.6.

I have managed to solve the problem by not loading mootools in the urls where the captcha loads. It is the only radical way by which I have been able to do it.

[dimov-cz]

1.6.0 without comp. layer is working for me

[dimov-cz]

The problematic code in compatibility mode is: /<1.5compat>/ Array.from = Array.convert; /</1.5compat>/

and in 1.5.1 and earlier version Array.from implementation which doesn't handle objects like MapIterate and Set.

For me it's worked in template index.php after : <?php unset($this->_scripts[$this->baseurl.'/media/system/js/mootools-core.js']); ?>

it removes core of mootools which can be used somewhere in your site. for example in my case it is used in virtuemart users/orders pages. removing it may lead to other issues.

for me it resolves problem with recaptcha but brings problems in admin part of site (e.g. on pages with availability to sort entities: articles, orders, etc). enabling compat layer even with fix form #374 brokes recaptcha.

I agree with you. This leads to other problems on the site. Spoilers and sliders break

[SaintAnd]

Unfortunately, this is the only option currently used. <?php if ($_SERVER["REQUEST_URI"] == "/internet-priemnaya/") { unset($this->_scripts[$this->baseurl.'/media/system/js/mootools-core.js']);} ?>

Using @sleemanj's original bind compatibility approach and the Array.from hint from @dimov-cz I've come up with the following which seems to be working for me (mootools 1.4.5):

// Add this BEFORE mootools is loaded

Function.prototype._nativeBind = Function.prototype.bind;
Array._nativeFrom = Array.from;

// Add this AFTER mootools is loaded

var isRecaptcha = function() {
    var stack = new Error().stack;
    if (!stack) {
        try {
            throw new Error();
        } catch (e) {
            stack = e.stack;
        }
    }
    return stack.match(/recaptcha/);
}

Function.prototype._mootoolsBind = Function.prototype.bind;
Array._mootoolsFrom = Array.from;

Function.prototype.bind = function (...args) {
    return isRecaptcha() ? this._nativeBind(...args) : this._mootoolsBind(...args);
};
Array.from = function (...args) {
    return isRecaptcha() ? this._nativeFrom(...args) : this._mootoolsFrom(...args);
};

I've not tested this thoroughly yet and there could be issues with it! Improvements welcome.

Okay, I have a much elegant solution for this.... Change this part of code

Array.from = function(item){
    if (item == null) return [];
    return (Type.isEnumerable(item) && typeof item != 'string') ? (typeOf(item) == 'array') ? item : slice.call(item) : [item];
};

with this

Array.from = function(item){
    if(new Error().stack.indexOf('recaptcha') >= 0) return [].slice.call(item); // Single line added for reCaptcha fix
    if (item == null) return [];
    return (Type.isEnumerable(item) && typeof item != 'string') ? (typeOf(item) == 'array') ? item : slice.call(item) : [item];
};

post the file if it works please

Cool, it seems to work... Could you write what the error was and what caused it? Thanks man!!!

Note that you may need to clear the browser cache for this to work.

This works without having to run a script before mootools is loaded:

// Add this AFTER mootools is loaded
(function fixMooToolsAndRecaptchaMapsIssueIffy() {
// restore native Array.from by getting the native implemenation from a new frame
var frame = document.createElement('iframe');
frame.sandbox = 'allow-same-origin';
document.body.appendChild(frame);
Array._nativeFrom = frame.contentWindow.Array.from
Function.prototype._nativeBind= frame.contentWindow.Function.prototype.bind
frame.remove();
var isRecaptchaOrMaps = function() {
    var stack = new Error().stack;
    if (!stack) {
        try {
            throw new Error();
        } catch (e) {
            stack = e.stack;
        }
    }
    return stack.match(/recaptcha/) || stack.match(/maps\.google\.com/);
}

Function.prototype._mootoolsBind = Function.prototype.bind;
Array._mootoolsFrom = Array.from;

Function.prototype.bind = function (...args) {
    return isRecaptchaOrMaps () ? this._nativeBind(...args) : this._mootoolsBind(...args);
};
Array.from = function (...args) {
    return isRecaptchaOrMaps () ? this._nativeFrom(...args) : this._mootoolsFrom(...args);
};
})();
