Threat Context

When AI agents operate autonomously, they often require broad permissions to execute tasks. However, if an agent is compromised via prompt injection or hallucinates a destructive command, it can cause significant damage to the host system.

The Path Traversal Guard rule acts as a deterministic safeguard. It continuously monitors the agent's runtime behavior and immediately intercepts any action that violates this rule, ensuring your infrastructure remains secure regardless of the agent's internal state.

Remediation & Logs

When this rule is triggered, OpenLeash will block the execution and generate an audit log. You can view these events in your OpenLeash dashboard or forward them to your SIEM.
