Shipday

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Shipday connector skill, with disclosed write/delete capabilities and approval guidance, but its one-time CLI installer command should be treated cautiously.

Install only if you intend to let an agent manage Shipday data through OOMOL. Review payloads before create/edit actions, require explicit confirmation for deletes, and avoid running the remote installer command unless you trust and verify the oo CLI source.

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

External Script Fetching

High

Supply Chain
Confidence

Finding

The skill recommends installing the CLI via a remote script piped directly into a shell (curl ... | bash). This pattern is dangerous because it executes network-fetched code without verification, making users vulnerable to supply-chain compromise, CDN/server hijack, TLS interception in misconfigured environments, or accidental execution of changed installer contents.

Finding

The description says to use this skill for "ANY Shipday request" and "Whenever a task involves Shipday," which is an extremely broad trigger description for a markdown skill file. It does not define boundaries, exclusions, or negative examples, so ordinary mentions of Shipday could match unintentionally.
