Check Point patched a critical flaw in its management servers that lets an unauthenticated attacker run code as root. Tracked as CVE-2026-91843 and scored 9.8, it is a stack overflow in the login process, which handles requests before a user authenticates, and it can be triggered by a login request carrying an overly long username. It affects Quantum management, Log, and Multi-Domain servers, through the Trusted Clients path. Customers with automatic updates are already protected, and others should apply the vendor's live patch. Check Point reports no exploitation yet, but this is the third serious management-server flaw it has disclosed in weeks, and compromising it means control over the whole firewall estate.
Check Point has fixed an actively exploited flaw in SmartConsole, the graphical admin panel used to manage its security products. CVE-2026-16232, rated 9.3, is an authentication bypass letting an unauthenticated remote attacker obtain a login token and authenticate with administrator privileges, after which they can alter security configuration and policy on a Security Management or Multi-Domain Management server. Exploitation requires the management server to be reachable from the internet with no restrictions on trusted GUI clients. The same update fixes a second critical authentication bypass and a Gaia Portal issue letting read-only users run commands as root.
