Cron Forge

Security checks for vulnerabilities and agentic risk

Overview

CronForge is a documentation-only cron template skill whose scheduling behavior is disclosed and aligned with its purpose.

Review any cron prompt before adding it, especially tasks that read inboxes, inspect systems, or post content publicly. Use isolated sessions where appropriate and periodically list/remove active crons you no longer need.

A.I.G

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

Finding
Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
