Responsible disclosure

How to report a security vulnerability to Mule, and what we commit to.

Version

Status
Draft, pending counsel review
Last updated

We welcome reports from security researchers and anyone who finds a weakness in www.mule.sh, the Mule Portal or a system Mule runs. This policy explains how to report and what we commit to. Our machine-readable contact is at /.well-known/security.txt.

How to report

Email juastins@icloud.com with "Security" in the subject. Include:

  • what you found and where (URL, system, component);
  • steps to reproduce, and any proof of concept;
  • the impact as you understand it;
  • how we can reach you.

Reports in English, Dutch, French or German are fine.

What we commit to

  • Acknowledge your report within 3 business days.
  • Keep you informed while we investigate and fix it.
  • Not take legal action against good-faith research that follows this policy.
  • Credit you, if you wish, once the issue is fixed.

Please

  • Test only against your own accounts and data. Do not access, change or delete other people's data.
  • Do not run denial-of-service tests, social engineering, physical attacks or spam.
  • Give us reasonable time to fix the issue before disclosing it publicly. We aim for 90 days or less.
  • Stop and tell us if you reach personal data, client records or credentials.

Out of scope

Client systems hosted by others; reports from automated scanners without a demonstrated impact; missing best-practice headers with no exploit; issues in third-party services, which should go to that provider.

We do not run a paid bug bounty at this time.
