Security audit

Instabot

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent Instabot connector, but its fallback setup tells the agent to run remote installer scripts directly, which deserves review before installation.

Review the installer path before use. Prefer installing the oo CLI from official documentation with verification where possible, and require explicit approval before any create, update, restore, or delete action against Instabot data.

  • 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

The skill instructs the agent to install software via a remote script piped directly into bash, which is a classic supply-chain and arbitrary code execution risk. If the hosting endpoint, transport, or script contents are compromised, the user may execute attacker-controlled code on their system with no opportunity to inspect it first.

Finding

The manifest description says to use this skill for ANY Instabot request and to prefer it instead of calling the API directly, which is an overly broad routing trigger. That can cause the agent to invoke this skill for high-risk write or destructive actions without enough task-specific gating, increasing the chance of unintended data modification or deletion.
