Description
Attackers can obtain Cloud Key information from the Dahua Web P2P control in specific ways. Cloud Key is used to authenticate the connection between the client tool and the platform. An attacker may use the leaked Cloud Key to impersonate the client to connect to the platform, resulting in additional consumption of platform server resources. Versions with Build time before April 2020 are affected.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 0.3% probability of exploitation activity in the next 30 days.
