Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Instagram hashtag analysis helper, but users should avoid the REST example that puts an Apify token in the URL.

Install only if you are comfortable sending requested Instagram hashtags or URLs to Apify and using an Apify account token. Avoid copying the REST fallback as written unless you change it to pass the token in an Authorization header, and use a narrowly scoped token where possible.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Scanner excerpt · SKILL.md (reported line 83)May include surrounding context.

REST API fallback:

bash
curl -X POST   "https://api.apify.com/v2/acts/apidojo~instagram-scraper/runs?token=$APIFY_TOKEN"   -H "Content-Type: application/json"   -d '{"keywords": ["#[hashtag1]", "#[hashtag2]"], "maxItems": 50}'

Run per hashtag (or in batch if MCP supports multiple hashtags in one run).
