CircleCI Security


At CircleCI, our top concern is protecting our users’ intellectual property
and sensitive secrets such as keys, tokens, and credentials.

Have a security concern about CircleCI?

We're confident in our implementation around matters such as email spoofing and DKIM records. However, here are some issues we would be excited to hear about:

  • Injection vulnerabilities
  • Authentication or session problems
  • Improper access to sensitive data
  • Broken access controls
  • Cross-site scripting
  • Anything from the OWASP Top 10 Project

Upon discovering a vulnerability, we ask that you act in a way to protect our users' data:

  • Inform us as soon as possible.
  • Test against fake data and accounts, not our users' private data (please ask if you'd like a free account to work on this).
  • Work with us to close the vulnerability before disclosing it to others.

Report your security concerns to CircleCI.

If you are reporting a sensitive issue, please encrypt your message using our security team's GPG key (ID: 0x4013DDA7, fingerprint: 3CD2 A48F 2071 61C0 B9B7 1AE2 6170 15B8 4013 DDA7)
