FreeAstroAPI

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent FreeAstroAPI connector helper with disclosed setup steps, though users should treat the CLI install command and account-connected data sharing carefully.

Install only if you are comfortable using OOMOL as an intermediary for FreeAstroAPI requests and sending the requested birth, location, date, or name data needed for calculations. Review the oo CLI installer source or official install guide before running the pipe-to-shell command, and do not run account login or connection setup unless the connector actually reports an authentication or connection error.

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

Finding

The skill instructs users to install software via a remote script piped directly into bash, which executes unreviewed network content immediately. If the install endpoint, transport, or upstream distribution is compromised, this becomes arbitrary code execution on the user's machine; in a skill context, this is especially risky because users may treat setup instructions as trusted and follow them without scrutiny.

Confidence

Finding

The description says to use this skill for ANY FreeAstroAPI request and whenever a task involves FreeAstroAPI, which is broad enough to trigger on mere mentions rather than clear user intent to invoke the tool. Over-broad invocation can cause unintended tool execution, unnecessary data disclosure to the connector, and confused-deputy behavior in agent workflows.
