TPSCheck

Security checks for vulnerabilities and agentic risk

Overview

The skill’s TPSCheck connector behavior is coherent, but its setup instructions include running a remote installer script directly in the shell.

Review the installer step before using this skill. Prefer installing the oo CLI from verified official documentation or a signed package, and avoid letting an agent run remote installer pipes automatically. Once the CLI is already installed and connected, the skill’s TPSCheck actions appear limited and purpose-aligned.

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

The skill instructs the agent/user to install software by piping a remotely fetched script directly into the shell (curl ... | bash). This creates a supply-chain and remote-code-execution risk: if the hosting domain, transport, or script content is compromised, arbitrary code will run immediately with the user's privileges, and the skill context explicitly encourages this as a fallback action.
