VulnerabilityHigh severity

No Behavioral Monitoring or Kill Switch

Agent actions are not logged step by step, drift from scope is not detected, and there is no fast way to stop agents or revoke their access.

Impact

Misbehaving agents run until a human happens to notice the damage.

Why this severity

Impact High × Likelihood Medium = High

Impact high: no containment once something goes wrong. Likelihood medium: the 2026 evaluation-agent incident ran for weeks before containment.

Impact High: Code execution, credential compromise, exposure of regulated or confidential data, irreversible actions, or system-wide failure.
Likelihood Medium: Publicly demonstrated against real products or in peer-reviewed research, or seen in the wild only with a prior foothold such as stolen credentials.

Remediation

  1. Log every plan, tool call, and result with agent identity.
  2. Alert on actions outside the agent's declared scope.
  3. Build one control that stops all instances and revokes tokens.

How to verify

Pattern

if (!scope.allows(action)) { alert('scope-drift', action); return killSwitch.halt(agent.id); }
