Responsible Vulnerability Disclosure

Follow this guide if you’ve found a vulnerability in one of SonarSource’s products or websites and you want to responsibly report it.

SonarSource customers with a support contract can report the vulnerability directly through the support channel.

Otherwise, send an email to

What we need from you:

  • Detail the steps you followed that make the vulnerability exploitable including any URLs or code you used. The more information you provide, the faster we can reproduce and fix the problem.
  • Please don’t send PDF, DOC, or EXE files or reports generated by DAST products. We will not look at them. We do accept images.

Focus areas:

  • Cross-site scripting (XSS)
  • SQL injection (SQLi)
  • Cross-site request forgery (CSRF)
  • Remote code execution (RCE)
  • Cookies not used for authentication or CSRF protection, not being marked as Secure or HTTPOnly
  • Data breaches, such as data of private projects or private organizations on SonarCloud.

How SonarSource rewards you?

It’s in our plans, but we don’t have a bug bounty program currently. Instead, if you accept it, we’ll put you in the Hall of Fame section of this guide under the name or nickname of your choice.

Public disclosure

You need to get our permission before disclosing an issue publicly. We’ll only consider your public disclosure request after we’ve fixed the reported vulnerability.

Hall of Fame

Thanks guys for having reported vulnerabilities privately, you rock!
