Description

I am loading a webpage with "Cloudflare Turnstile" applied.

However, the webview of flutter_inappwebview seems to have a security error.

All other browsers (PC, Mobile) are passing fine.

I would like to know what the problem is.

If anyone has any knowledge about this issue, please help me.

Thank you.

Steps to reproduce

My InAppWebViewSettings

var inAppWebViewSettings = InAppWebViewSettings(
  useShouldOverrideUrlLoading: true,

  transparentBackground: true,
  javaScriptCanOpenWindowsAutomatically: true,
  allowFileAccessFromFileURLs: true,
  allowUniversalAccessFromFileURLs: true,

  verticalScrollBarEnabled: false,

  horizontalScrollBarEnabled: false,

NOTE: This comment is auto-generated.

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

Hi everyone, I'm an engineer working on Turnstile at Cloudflare.

I'm afraid I'm unable to reproduce the issue, could you follow https://developers.cloudflare.com/turnstile/frequently-asked-questions/#how-can-i-obtain-the-ray-id-or-qr-code-for-troubleshooting and post the rayID or QR code here so I can follow-up?

Hello! Thank you very much for helping to figure out the problem! I will try to assist; for me, it's quite straightforward, I turn on my personal VPN, which operates through an IP address of a server on DigitalOcean, attempt to access my app that uses this WebView plugin, open the link https://dash.cloudflare.com/ just to reach the point where Cloudflare shows me the robot check. I try to pass it and then I get errors in the logs, below I attach typical logs from the console. In turn, I tried to look at the traffic in a regular browser while passing this check and saw that the browser processes resources whose address starts with blob:https. But in the logs, I do not see that the WebView plugin tries to load such resources in any way. It seems like WebView can't work with blob:https right out of the box.

How to get to the check doesn't matter at all, I just found the fastest way for myself to open the Cloudflare check.

Thanks, @RMatushkin!

Screenshot of the check page:

What happens when you click the "Verify you are human" button? Do you get a failure icon and text?

I tried to look at the traffic in a regular browser while passing this check and saw that the browser processes resources whose address starts with blob:https.

We used to have navigations to blob: URLs but found those were incompatible with this lib when used together with navigation delegates. What you see in Dev Tools right now isn't a fetch/XHR, and as far as we're aware those don't pose an issue.

I'm unable to reproduce the issue, both with a basic example of flutter_inappwebview, https://github.com/pichillilorenzo/flutter_browser_app, and I'm afraid I don't see what the issue you're experiencing might be by looking at the logs you provided.

Do you only experience the issue on iOS? I see the reports about Android, but I can't reproduce those, even with the current latest few WebView versions.

RMatushkin commented 1 year ago

Hey @migueldemoura!

What happens when you click the "Verify you are human" button? Do you get a failure icon and text?

After clicking, a looping loading appears, in other words, nothing happens for a very long time. Then the square for clicking appears again.

We used to have navigations to blob: URLs but found those were incompatible with this lib when used together with navigation delegates. What you see in Dev Tools right now isn't a fetch/XHR, and as far as we're aware those don't pose an issue.

Interesting fact, I really hope that blob resources really don’t have any effect.

Do you only experience the issue on iOS? I see the reports about Android, but I can't reproduce those, even with the current latest few WebView versions.

I use exclusively iOS devices, I have no idea how the CloudFlare check behaves on Android devices.

Plugin version: v6.0.0-beta.25

WebView settings:

initialSettings: InAppWebViewSettings(
  preferredContentMode: UserPreferredContentMode.MOBILE,
  transparentBackground: true,
  supportZoom: false,
  verticalScrollBarEnabled: false,
  horizontalScrollBarEnabled: false,
  javaScriptCanOpenWindowsAutomatically: true,
  allowUniversalAccessFromFileURLs: true,
  accessibilityIgnoresInvertColors: true,
  isFraudulentWebsiteWarningEnabled: false,
  allowsAirPlayForMediaPlayback: false,
  allowsPictureInPictureMediaPlayback: false,
  allowsInlineMediaPlayback: true,
  geolocationEnabled: false,
)

Used link: https://dash.cloudflare.com

Here, I specifically recorded a short video that shows the problem in action:

https://github.com/pichillilorenzo/flutter_inappwebview/assets/54648323/41c0345c-8228-47c6-be3e-f0a79d8dabd8

And here is logs file from the video: logs.txt

Diniboy1123 commented 1 year ago

I can reproduce this on Android using my own test app and the above mentioned flutter_browser_app example. I could see the following in the developer console: Uncaught SecurityError: Failed to read a named property 'flutter_inappwebview' from 'Window': Blocked a frame with origin "https://challenges.cloudflare.com" from accessing a frame with origin "https://mydomain.tld". Protocols, domains, and ports must match. I assume this should be related. I see the captcha, click on it, it seems to succeed and then the challenge page just reloads once again.

Any updates?

pichillilorenzo commented 11 months ago

It should be fixed now for iOS on the latest release.

Instead, for Android WebView, it seems the problem could be related to the X-Requested-With HTTP header sent automatically by native WebView for each HTTP request: https://community.cloudflare.com/t/turnstile-always-fails-in-a-webview/423520/5 Currently, there is no official Android WebView API to disable this HTTP header, as it should be already removed starting from androidx.webkit:webkit:1.6.0-alpha02:

I just took the source code from the commit, rebuilt my iOS app based on this version, and saw that the issue with Cloudflare Turnstile hasn't been resolved. I looked at the changes you made, but I don't understand how they relate to the current issue. You only fixed the logging in the file ConsoleLogJS.swift. Will there be another commit that fixes the problem?

pichillilorenzo commented 11 months ago

Try to run flutter pub upgrade with latest 6 version . For some reason, the console wrapper implemented for iOS seemed to cause the issue, I don’t know why. I tried removing completely that implementation and it worked, so I tried to deep understand what was causing the issue and I came up with that.

pichillilorenzo commented 11 months ago

I tested both links https://dash.cloudflare.com/ and https://app.1inch.io/ on real iPhone and it worked. Without this fix, I was having same issue.

Hmm, I tried the official webview flutter plugin and from what I remember Turnstile was passing fine there on Android.

RMatushkin commented 11 months ago

@pichillilorenzo Thank you very much for your help! Indeed, after I ran the flutter pub upgrade command, the problem was resolved even on the iOS simulator.

pichillilorenzo commented 11 months ago

@RMatushkin 👍 that’s because I published a new minor version with the fix on the iOS-specific implementation package, but the main plugin has not been updated. Newer plugin version has been implemented as a Federated Flutter plugin.

@AlexDochioiu hmm I will try and check again.

@pichillilorenzo I just read your console patch for the iOS version, and indeed that was likely the root cause for the previous issue. Can also confirm that the presence of X-Requested-With should not cause the Turnstile failure for Android WebViews. We do have substancial traffic from these, so I presume there's some modifications being applied which would lead to the failures.

I was unable to reproduce this on Android, but would like to get this working for you all. When it fails, could you submit feedback via the Having trouble? dialog that appears when it fails and adding https://github.com/pichillilorenzo/flutter_inappwebview/issues/1738 to the description?

pichillilorenzo commented 11 months ago

Fixed also on Android now! You can update to the newly published plugin version 6.0.0-rc.1.

@migueldemoura the error was caused by the same code spot on Android. I don't know why the javascript wrapper around the window.console was causing the issue. It doesn't make any sense to me, but it seems the javascript code used by CloudFlare is doing something with the window.console object. Somehow, If the window.console functions (log, error, etc.) are wrapped with a function that is long X characters (I don't know the maximum number of chars but I mean literally the string characters), it just breaks. In fact, my fixes are just about moving out the wrapper code the needed logic.

Here is just an example of what I'm talking about. Think that you want to wrap the console.log function for whatever reason, you can do something like:

var oldConsoleLog = console.log;
console.log = function() {
    var message = '';
    for (var i in arguments) {
        message += message === '' ? arguments[i] : ' ' + arguments[i];
    }
    oldConsoleLog.apply(null, arguments, 'myValue');
}

This wrapping would cause the issue that we were having here.

Instead, this code would simply work:

var oldConsoleLog = console.log;
console.log = function() {
    oldConsoleLog.apply(null, arguments, 'myValue');
}

I also tried adding just code comments or whitespaces, and it would still break, so it seems like it depends on how many characters the log functions of the window.console object are made up of.

As I said, it doesn't make any sense to me on why this would cause the issue on Cloudflare. 🤷‍♂️

ttb-inc commented 11 months ago

I checked the new version 6.0.0-rc.1, and it works well on both Android and iOS. Thank you very much.

endyquang commented 9 months ago

I still see this error on newest version 6.0.0 on iOS (Flutter 3.16.5, iOS 16.x). It works on Android but stuck forever on iOS.

Steps to produce:

After adding a UserScript to override console.clear = (() => {});. Open the inspector, select preserve log, this is the stack trace leading to the console wrapper.

Screenshot 2024-01-30 at 16 49 47

@pichillilorenzo what about an option to disable this console wrapper? An additional reason is on Android, this wrapper currently converts all arguments into string, which makes it difficult to debug, because we can't see the logged objects properly on the chrome inspector.

a00012025 commented 9 months ago

Hi, I can reproduce this issue on iOS using latest version of the library, with this URL: https://etherscan.io/myaccount

pichillilorenzo commented 9 months ago

Thanks for the reports, I will check it as soon as possible.

@endyquang about Android, I should be able to change the current wrapper without impacting the Chrome debug console. The current implementation was done that way to match the same onConsoleMessage event we have on iOS and macOS. It seems that on Android, the native WebView event that is responsible for getting console messages will take only the first argument. So, that’s the reason about the current implementation.

            return NavigationActionPolicy.ALLOW;
          },

Seems like other web views also have similar issues: https://community.cloudflare.com/t/turnstile-no-longer-working-inside-of-ios-apps-in-wkwebview/637940/8

Is there a similar alternative for the in app web view to use for originWhitelist in case that is the issue?

Hey @stickeerehan, originWhitelist is usually the issue, otherwise it should work as we test against this specific implementation w/ its defaults.

Looks like in my case the culprit after trial and error was the setting 'useShouldInterceptAjaxRequest' - having this breaks the Cloudflare turnstile. Can confirm it works with the default settings

@endyquang I released flutter_inappwebview_android version 1.1.2 for the latest plugin version removing the custom wrapper as the native WebChromeClient.onConsoleMessage event seems to be working correctly, so you should see the logged objects properly on the chrome inspector.
