Report Bugs

There are a couple bug trackers relevant to WebRTC:

* Anyone with a Google account can file bugs and they’re continuously triaged by Chrome and WebRTC engineers.

How to File a Good Bug Report

Please include as many relevant details as possible.

Filing a Security Bug

The WebRTC team takes security very seriously. If you find a vulnerability in WebRTC, please file a Chromium security bug, even if the bug only affects native WebRTC code and not Chromium.

A history of fixed Chromium security bugs is best found via security notes in Stable Channel updates on the Google Chrome releases blog.

You can also find fixed, publicly visible Type=Bug-Security bugs in the issue tracker (note: security bugs normally become publicly visible 14 weeks after they are fixed). If there is a bug in WebRTC code that Chromium isn’t using (such as the Java/ObjC wrappers for Android/iOS) we will announce fixes separately on discuss-webrtc.

List of all disclosed native-only security bugs.

Note that we will generally NOT merge security fixes backwards to any branches, so if you’re using older branches it’s your responsibility to make sure the relevant security fixes get merged.

Receiving notifications about security bugs in Chrome

To get automatic notifications about activity/comments in security bugs in Chrome you need to be either explicitly cc:d on specific bugs (by someone who has access to the bug) or be part of a special mailing list for all security bug notifications. To get on that list you have to apply to the Chrome Security team, see more about this on the Chrome Security page under “How can I get access to Chromium vulnerabilities?” at the bottom of the page.

Please note that Chrome’s security-notify list will receive notifications about all security bugs in Chrome and not just the WebRTC ones. Normally it shouldn’t be a problem to figure out whether an issue affects WebRTC since it will most likely be tagged with one of the WebRTC-related components (one of Blink>WebRTC, Blink>GetUserMedia, Blink>MediaStream, Blink>MediaRecording) or their sub- components.

Also note that access granted by the list will only apply to bugs of Type=Bug- Security. Not all bugs with crashes, memory leaks and other potential vulnerabilities are marked as Bug-Security though. You can read more about what categories of bugs are deemed security bugs in the Severity Guidelines for Security Issues and also on the Security FAQ page.

Example Data Points

  • Version of the browser/app

    • For Chrome: copy/paste from chrome://version

    • For WebRTC native code: if applicable, include the branch (e.g. trunk) and WebRTC revision (e.g. r8207) your application uses

  • Operating system (Windows, Mac, Linux, Android, iOS, etc.) and version (e.g. Windows 7, OS X 10.9, Ubuntu 14, etc.)

  • Hardware platform/device model (e.g. PC, Mac, Samsung 4S, Nexus 7, iPhone 5S, iPad Air 2 etc)

  • Camera and microphone model and version (if applicable)

    • For Chrome audio and video device issues, please run the tests at <https://test.webrtc.org>. After the tests finish running, click the bug icon at the top, download the report, and attach the report to the issue tracker.

  • Web site URL

  • Reproduction steps: detailed information on how to reproduce the bug. If applicable, please either attach or link to a minimal test page in HTML+JavaScript.

  • For crashes

    • If you experience a crash while using Chrome, please include a crash ID by following these instructions.

    • If you experience a crash while using WebRTC native code, please include the full stacktrace.

  • For functional issues or ICE issues, in either Chrome or a native application, please gather a native log.

  • For connectivity issues on Chrome, ensure chrome://webrtc-internals is open in another tab before starting the call and while the call is in progress,

    • expand the Create Dump section,

    • click the Download the PeerConnection updates and stats data button. You will be prompted to save the dump to your local machine. Please attach that dump to the bug report.

  • For audio quality issues on Chrome, while the call is in progress,

    • please open chrome://webrtc-internals in another tab,

    • expand the Create Dump section,

    • fill in the Enable diagnostic audio recordings checkbox. You will be prompted to save the recording to your local machine. After ending the call, attach the recording to the bug.

  • For echo issues, please try to capture an audio recording from the side that is generating the echo, not the side that hears the echo. For example, if UserA and UserB are in a call, and UserA hears herself speak, please obtain an audio recording from UserB.
