Bug Bounty Programme


Cloudsmith aims to keep its Service safe for everyone, and data security is of utmost priority. If you are a security researcher and have discovered a security vulnerability in the Service, we appreciate your help in disclosing it to us privately and giving us an opportunity to fix it before publishing technical details.

Cloudsmith will engage with security researchers when vulnerabilities are reported to us as described here. We will validate, respond, and fix vulnerabilities in support of our commitment to security and privacy. We won’t take legal action against, suspend, or terminate access to the Service of those who discover and report security vulnerabilities responsibly. Cloudsmith reserves all of its legal rights in the event of any noncompliance.

If you identify a verified security vulnerability in compliance with this Security Disclosure Policy, Cloudsmith commits to:

  • Acknowledge receipt of your vulnerability report in a timely manner;
  • Notify you when the vulnerability is fixed; and
  • Publicly thank you for your responsible disclosure and for helping us stay safe.

Please note that in absolutely no event are you permitted to access, download or modify data residing in any other Account, or one that is not registered to you; unless permission is expressly provided by the Account Owner.

Bug Bounties / Hall of Fame

We are pleased to offer thanks and/or a bounty reward for vulnerability information that helps us protect our customers as thanks to the security researchers who choose to participate in our bug bounty program. This will range from the public thanks to a small monetary amount or loot of some sort (depending on our budget). Cloudsmith will decide the bounty reward at our sole discretion, and all decisions are final.


  • Upon acknowledgment of a viable exploit we will discuss the options with the reporter.
  • We will add the reporter's name/link to the Hall of Fame alongside exploit details.
  • If a bounty was determined this will be issued on resolution exploit resolution.

If a monetary award is provided as a bounty then you are responsible for paying any taxes associated with the reward. We are obliged by law to report any such awards to the tax authorities, so please ensure that you handle this appropriately.
