The reporter visits "SlowMist Zone" website and goes to "Submit Bug Bounty" (URL：https://slowmist.io/en/bug-bounty.html) to submit a threat intelligence. (Status: to be review)
1. Within one working day, the SlowMist Security Team will confirm the threat intelligence report from the "SlowMist Zone", follow up, evaluate the problem, and feed the intelligence back to the KuCoin contact person in the meantime (status: under review).
2. Within three working days, the KuCoin technical team will deal with the problem, draw conclusions and record points (status: confirmed / ignored). They will communicate with the reporter if necessary, and ask the reporter for assistance.
1. The KuCoin business department shall repair the security problems in the threat intelligence and update online (status: repaired). The repairing timeframe depends on the problem severity and the repair difficulty. Generally speaking, it is within 24 hours for the critical and high-risk problems, within 3 working days for the medium-risk problems, and within 7 working days for the low-risk problems. The App security issue is limited by the version release, and the repairing timeframe is on a case-by-case basis.
2. The reporter will review whether the security problem has been repaired (Status: reviewed/reviewed with
3. After the reporter confirms that the security problem is repaired, the KuCoin technical team will inform the SlowMist Security Team of the conclusion and the vulnerability score. They will issue rewards with the SlowMist Security Team (status: completed).

A critical vulnerability refers to the vulnerability occurs in the core business system (the core control system, field control, business distribution system, fortress machine and other control systems that can manage a large number of systems). It can cause a severe impact, gain business system control access (depending on the actual situation), gain core system management staff access, and even control the core system.
It is including but not limited to:
- Multiple devices access in the internal network.
- Gain core backend super administrator access, leak enterprise core data and cause a severe impact.
- Smart contract overflow and conditional competition vulnerability.
- Gain system access (getshell, command execution, etc.)
- System SQL injection (backend vulnerability degradation, prioritization of package submission as appropriate)
- Gain unauthorized access to the sensitive information, including but not limited to, the direct access to the management background by bypassing authentication, brute force attackable backend passwords, and to obtain SSRF of sensitive information in the internal network, etc.)
- Arbitrarily document reading
- XXE vulnerability that can access any information
- Unauthorized operation that involves money, payment logic bypassing (need to be successfully utilized)
- Serious logical design defects and process defects. This includes but is not limited to arbitrarily batch access to accounts, logic vulnerability involving enterprise core business, etc., except for verification code explosion
- Other vulnerabilities that affect users on a large scale. This includes but is not limited to the storage XSS that can be automatically propagated on the important pages, and the storage XSS that can access administrator authentication information and can be successfully utilized
- Leakage of a lot of source code
- The permission control defects in the smart contract
- The vulnerability that can affect users by the interaction part. It includes but is not limited to the storage XSS on general pages, CSRF involving core business, etc
- General unauthorized operation. It includes but is not limited to modify user data and perform user operation by bypassing restrictions
- Denial-of-service vulnerabilities. It includes but is not limited to the remote denial-of-service vulnerabilities caused by denial-of-service of web applications
- The vulnerabilities caused by a successful explosion with the system sensitive operation, such as any account login and password access, etc. due to verification code logic defects
- The leakage of locally-stored sensitive authentication key information, which needs to be able to use effectively
- Local denial-of-service vulnerabilities. It includes but is not limited to the client local denial-of-service (parsing file formats, crashes generated by network protocols), problems that are caused by Android component permission exposure, general application access, etc.
- General information leakage. This includes but is not limited to Web path traversal, system path traversal, directory browsing, etc
- Reflective type XSS (including DOM XSS/Flash XSS)
- General CSRF
- URL skip vulnerability
- SMS bombs, mail bombs (each system only accepts one type of this vulnerability).
- Other vulnerabilities that are less harmful and cannot be proven to be harmful (such as CORS
vulnerability that cannot access sensitive information)
- No return value and no in-depth utilization of successful SSRF
- Enterprise Mailbox Vulnerability
Vulnerabilities that are not accepted at the moment (even if such a vulnerability is submitted, it will be ignored)
- Theoretical vulnerabilities without actual proof of the concept
- Email verification defects, expiration of password reset links, and password complexity policies
- Invalid or missing SPF (Sender Policy Framework) records (incomplete or missing SPF/DKIM/DMARC)
- Clickjacking/UI redressing with minimal security impact
- Email or mobile enumeration (e.g.: the ability to identify emails through password resetting)
- Information leakage with minimal security impact (e.g: stack traces, path disclosure, directory listings, logs)
- Internally known issues, recurring issues, or issues already published
- Vulnerabilities only applicable on outdated versions of browsers or platforms
- Vulnerabilities related to auto-fill web forms
- Use of vulnerable libraries already known without actual proof of concept
- Lack of security flags in cookies
- Issues related to unsafe SSL/TLS cipher suites or protocol version
- Content spoofing
- Issues related to cache control
- Vulnerabilities exposing internal IP addresses or domains
- Lack of security headers that do not lead to direct exploitation
- CSRF with negligible security impact (e.g.: added to favorites, and subscribe non-vital features)
- Vulnerabilities that require root/jailbreak
- Vulnerabilities that require physical access to the device of users
- Issues with no security impact (e.g.: failure to load a web page)
- Assets not belonging to KuCoin
- Phishing (e.g.: HTTP basic authentication phishing)
