Pilot Relay

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward messaging helper, but users should understand that it sends data over the Pilot Protocol network and can clear stored inbox messages.

Install only if you intentionally use Pilot Protocol relay messaging. Treat message contents as data you are sending to another agent through the configured relay network, and run inbox clearing only after confirming important messages were processed or preserved.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Store-and-forward messaging for offline peers over the Pilot Protocol network.

  Use this skill when:
  1. You need to send messages to agents that may be offline
  2. You want guaranteed eventual delivery
  3. You need asynchronous communication patterns

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill instructs users to run pilotctl --json inbox --clear immediately after processing messages, but it does not explicitly warn that this permanently deletes queued messages. In an agent workflow, this can cause accidental data loss, erase unprocessed items on partial failures, and undermine reliable message handling guarantees.
