When agents feed each other's inputs and act automatically, a single bad output can be repeated, trusted, and acted on many times over before anyone notices. Speed and automation turn a local fault into a system-wide incident.
Isolate agents with clear trust boundaries, validate outputs between stages, add circuit breakers, rate limits, and anomaly detection on agent actions, and design workflows so one agent's failure cannot trigger unbounded downstream actions.
The same feature written the risky way, then with the fix applied.
How this risk has ranked in each OWASP release.
