Auth bypass in Checkpoint Multi-Domain Security Management
CVE-2026-16232
An authentication bypass vulnerability in the Check Point SmartConsole login process allows an unauthenticated remote attacker to obtain an application login token and use it to authenticate with full administrative privileges. Successful exploitation allows the attacker to modify security policies and security configurations. Remote exploitation requires internet access to the Management Server IP address and a configuration that does not restrict Trusted Clients. Check Point is aware that this vulnerability is being exploited and has affected a very small number of customers.
