Pilot Inbox

Security checks for vulnerabilities and agentic risk

Overview

This inbox skill is a small, disclosed set of Pilot Protocol CLI commands, with explicit cleanup commands that users should run carefully because they can clear inbox items or received files.

Before installing or using it, treat the --clear examples as destructive maintenance commands: review inbox and received-file contents first, and only run those commands when you intentionally want to remove those Pilot Protocol items. The ordinary inbox, received, task list, and pending commands are inspection-oriented.

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

Description-Behavior Mismatch

Finding

The skill is presented as a unified inbox for review and triage, but it also documents destructive clearing operations that can delete inbox contents or received files. In an agent setting, this creates a mismatch between expected read-only behavior and actual side effects, increasing the risk of accidental data loss if the commands are copied or invoked without careful review.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The documented --clear operations perform destructive actions without any warning, confirmation, or safety guidance. Because the skill is intended for inbox inspection, users or downstream agents may assume the commands are safe to run, leading to irreversible removal of messages or files during routine triage workflows.
