Nanonets OCR

Security checks for vulnerabilities and agentic risk

Overview

This skill is a documented connector for Nanonets DocStrange that uploads user-selected documents to an external extraction API, with the credential and privacy implications disclosed.

Install only if you are comfortable sending selected documents to Nanonets' external extraction service. Prefer DOCSTRANGE_API_KEY in an environment variable or secret store, avoid uploading highly sensitive PII until you have reviewed the provider's retention and compliance terms, and keep API keys scoped and rotated where possible.

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

**Security Note:** If storing API keys in `~/.openclaw/openclaw.json`:
- Set file permissions: `chmod 600 ~/.openclaw/openclaw.json`
- Never commit this file to version control
- Prefer environment variables or your agent's secret store when possible
- Rotate keys regularly and limit API key permissions if supported
