Flux CVE Registration

The Flux Team, Community and Foundation are proud to announce Flux’s application to become a CNA.

A secure environment is only possible through the rapid sharing and deployment of knowledge. Flux aims to contribute to this through the Common Vulnerabilities and Exposures (CVE) organization, run and operated by Mitre.

CVE is a central database of known vulnerabilities, it is used as a source by many anti-malware and anti-virus software providers. Becoming part of the standard setting family would be paying back to the community the trust they have shown in us so far and help us facilitate a safer environment for all.

The Flux team strives to deliver a strong effort in support of all CVE’s efforts and values.

Please, contribute to our code!

Responsible Disclosure Policy

To encourage responsible disclosure, no legal action shall be taken against you, provided you adhere to the following points:

  1. The FLUX Blockchain and nodes: Any and all exploits be confined to a private testnet or regtest for validation purposes. Any code modifications carried out to run exploits need to be disclosed along with the effects for full validation.

  2. For the FluxOS distributed operating system, any and all exploits are confined to their own nodes for validation purposes. Should additional nodes be required to fully validate more serious/extensive effects “ripple attacks”, the Flux team will assist with a private testnet.

  3. Submissions can only be made to using the attached PGP keys for encryption. This is a requirement for any reward.

  4. Include an email for responses in your report.

  5. Adhere to timeframes laid out in initial confirmation of report emails. As we are a small team, the only absolute promise we can make is an acknowledgement within 24 hours which will include full timeframes for remedial action, public disclosure as well as publication and acknowledgement.

All bugs will be evaluated according to the CVSS scoring scale and rewarded accordingly. The CVSS levels are:






3000-5000 Flux



1000-3000 Flux



250-1000 Flux



250 Flux



10 Flux

How it works:

  1. Adhere to the Responsible Disclosure Policy

  2. Make all possible effort to not interrupt or degrade our service.

  3. Do not attempt to gain unauthorized access to user accounts, assets or information (use your own account/accounts to test against).

  4. Do not copy or modify any files or data, including permissions, and do not intentionally view or access any data beyond what is needed to prove the vulnerability.

  5. Do not exploit a security issue you discover beyond the point of validation on own accounts/nodes.

  6. We publish a list of researchers who have submitted valid security reports.

  7. However, should you wish to remain anonymous, we will respect your privacy.

  8. We reserve the right to determine timeframes for publishing reports (and accompanying updates) pertaining to each instance. However, we will provide best effort information to you on all such issues.

Out-of-scope Service

We have the right to remove you from the Bug Bounty Program and disqualify you from receiving any bounty rewards if you: Are in violation of any national, state, or local law or regulation

Qualifying Vulnerabilities

  1. Injection flaws such as SQL, noSQL, Mongodb, OS injection that tricks command interpreter into executing unintended commands without proper authorization.

  2. Broken authentication/session management that allows compromise of passwords, keys, or session tokens

  3. Sensitive data exposure due to improper protection of data via insecure API or flaw in cryptography implementation

  4. Cross-Site Scripting (XSS)

  5. Cross-Site Request Forgery (CSRF) for sensitive functions in a privileged context

  6. Remote code execution (RCE)

  7. Insecure Direct Object References

  8. Privilege Escalation

  9. Significant Security Misconfiguration (when not caused by user)

  10. Directory Traversal

  11. Open Redirects

  12. Spoofing enablement

  13. Attacks of any type on the docker containers hosted on the Flux network.

  14. Any significant abuse-related methodologies that could lead to significant harm

The above list is by no means exhaustive, so if you have something not on it and not on the excluded list, please reach out, it is covered.

Non-Qualifying Vulnerabilities

  1. Non-original or previously disclosed/reported bugs (with fixes currently underway).

  2. Non-technical attacks such as social engineering, phishing, or physical attacks against entities or infrastructure.

  3. Any degrading/damaging the reliability or integrity of our services (such as DDoS attacks, man in the middle attacks, spamming, and similar questionable acts)

  4. Any software not directly produced by the Flux Team

  5. Domains hosted by third parties (e.g.: Github, Gitlab, etc)

  6. Subdomains operated by third parties (e.g:

  7. Any Flux branded services operated by third parties

  8. Network hijacks, man in the middle, ss7 or similar.

Process flow:

Send an email using the below PGP keys is the only email to use. Failing to use the attached PGP keys for the bug report will invalidate any submissions.

  1. Write up a report on your findings.

  2. PGP Encrypt the report with keys from URL

  3. Within 24 hours you will recive an acknowledgement

  4. Adhere to timeline and additional information requests from the Flux team outlined in the acknowledgement email.

  5. Discuss publication times and names.

  6. Collect bounty, if approved.

  7. Get published under the advisory policy

Process flow:

Flux will immediately upon the discovery and initial remediation of security breaches undertake to inform the community and user base as a whole to the largest broadest extent possible.

Initial communication from Flux may not necessarily include details of the vulnerability if the purpose of such an advisory is to have end-users update potentially compromised software.

As soon as a reasonable (severity dependent) percentage of users have updated their software, Flux will do full and in depth disclosure with CVE reports published at URL. Security researchers who choose to contribute towards the wellbeing of Flux and the wider community will be acknowledged in the posts. However, should they request privacy, the Flux team will respect that.

The Flux Team reserves the right to determine timeframes for publication in accordance with best overall security practices for end-users.

The exact methods of communication of advisories will include but are not limited to publishing on URL as well as announcement through Flux’s social media channels.
