Google Trends RSS

Security checks for vulnerabilities and agentic risk

Overview

This skill fetches public Google Trends RSS data and optionally saves user-requested exports, with no evidence of hidden behavior, persistence, credential use, or destructive actions.

Installers should understand that the skill contacts Google Trends over the network and can write JSON or CSV exports when --out is used. Use trusted workspace or temporary output paths and review generated files before importing them into Sheets or reports.

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
The skill invokes a networked script and supports writing output to arbitrary file paths via `--out`, but the manifest declares no explicit tool scope or permissions. That creates an authorization gap: an agent may use network and file-write capabilities without clear least-privilege boundaries, increasing the chance of unintended data exfiltration, unsafe writes, or policy bypass in environments that rely on manifest-declared constraints.
