{"id":"CVE-2026-26009","summary":"Catalyst Affected by Remote Code Execution as Root via Containerized Install Script Execution","details":"Catalyst is a platform built for enterprise game server hosts, game communities, and billing panel integrations. Install scripts defined in server templates execute directly on the host operating system as root via bash -c, with no sandboxing or containerization. Any user with template.create or template.update permission can define arbitrary shell commands that achieve full root-level remote code execution on every node machine in the cluster.
