No technology is perfect, and curl 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 products, we encourage you to notify us. We welcome working with you to resolve the issue promptly.

Disclosure Policy

  • Let us know as soon as possible upon discovery of a potential security issue, and we'll make every effort to quickly resolve the issue.
  • Provide us a reasonable amount of time to resolve the issue before any disclosure to the public or a third-party.
  • Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service.


While researching, we'd like to ask you to refrain from:

  • Denial of service
  • Spamming
  • Social engineering (including phishing) of curl developers

Safe Harbor

Any activities conducted in a manner consistent with this policy will be considered authorized conduct and we will not initiate legal action against you. If legal action is initiated by a third party against you in connection with activities conducted under this policy, we will take steps to make it known that your actions were conducted in compliance with this policy.

Valid issues

Any security problem in a released curl/libcurl version that hasn't already been reported may be subject for a bounty.

Experiments are excluded!

Vulnerabilities in features which are off by default and documented as experimental, are not eligible for a reward.

Issues with our infrastructure

Any infrastructure issue that you may find is out of the policy unless it affects the source packaging/distribution.

The wiki is word editable

It is on purpose. It is a wiki. If you change or add non-curl related contents to prove a point, we consider that abuse.

Thank you for helping keep curl and our users safe!
