Bug bounty program

No technology is perfect, and Uploadcare believes that working with skilled security researchers across the globe is crucial in identifying weaknesses in any technology. If you believe you've found a security issue in our product or service, we encourage you to notify us. We welcome working with you to resolve the issue promptly.

To show our appreciation of responsible security researchers, Uploadcare offers a monetary bounty for reports of qualifying security vulnerabilities. Reward amounts will vary based upon the severity of the reported vulnerability, and eligibility is at our sole discretion.

Contact us at bugbounty@uploadcare.com.
