Found a vulnerability?

When you've found a vulnerability please consider the following:

  1. Ensure the vulnerability relates directly to the Pusher service or an official library
    Although we will try and help, we can't be responsible for issues arising from libraries written by third party developers. Those questions are best suited to the individual library authors.

  2. Safely disclose the vulnerability
    Upon finding a vulnerability we ask that you get in touch and report it to us. Please avoid making details of the vulnerability public.

  3. Do not negatively affect other users
    If you've discovered a vulnerability the would allow you to negatively affect other users please report this to us. Please do not test a vulnerability on any other users.

  4. Provide as much information as possible
    It makes it a lot easier for us to verify the validity of a report if there is sufficient information provided. Screenshots, video recordings and detailed steps to reproduce tend to be the best ways of conveying the vulnerability.

If the above apply, then send an email to
