How fast can a Marimo RCE reach an SSH bastion?Sysdig researchers showed a human attacker chaining a remote code execution flaw in the Marimo Python notebook to reach an SSH bastion in about eight seconds — no AI agent required.What happened: In research published by Sysdig, an operator exploited a remote code execution (RCE) bug in Marimo, an open-source Python notebook, then pivoted to the environment's SSH bastion in eight seconds flat. The run was entirely human-driven, undercutting the assumption that only AI-powered tooling can move at that speed. The findings landed alongside warnings that AI is compressing the gap between vulnerability disclosure and exploitation.Key numbers: 8 seconds from RCE trigger to SSH bastion access1 vulnerability was enough to complete the chain0 AI agents involved; a human did it by handWhy it matters: If one person can go from a fresh bug to a jump host in seconds, patch windows measured in days are already lost.Bottom line: Speed is the exploit
