The Tokenlon business department shall repair the security problems in the threat intelligence and update online (status: repaired).

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.
The reporter will review whether the security problem has been repaired (Status: reviewed/reviewed with objection).
After the reporter confirms that the security problem is repaired, the Tokenlon technical team will inform the Bugrap Security Team of the conclusion and the vulnerability score. Tokenlon will issue rewards with the Bugrap Security Team (status: completed).

Critical Vulnerabilities
A critical vulnerability refers to the vulnerability that occurs to the core business of a smart contract, which could result in the tokens owned by the platform or users being transferred, stolen, or frozen. Or taking control of the business system, and thus the core system getting affected.
A high-risk vulnerability refers to that owing to the incorrect processing of the contract programs, the contract get exploited and arbitraged, involving money loss but not on a large-scale. Or contract defects like smart contract overflow, precision problems, and system check bypass.
A medium-risk vulnerability refers to a vulnerability that can affect users only by interaction. For example, the data of the user's operation is affected due to improper page access. (Tokenlon.im)
