The full name of Brovi PSIRT is (Brovi Product Security Incident Response Team). Brovi PSIRT is a dedicated team responsible for receiving, verifying, and disclosing vulnerabilities related to Zhuoyi products. Brovi defines a vulnerability as a security issue that can be exploited in a product, and once exploited by an attacker, it can cause damage to the integrity, availability, or confidentiality of the product. A vulnerability is not equivalent to a quality defect. A quality defect is triggered without the need for an attacker to exploit it when the triggering condition is met, while a vulnerability must be exploited and triggered by an attacker.
