Security checks for vulnerabilities and agentic risk

Overview

ClawScan rates this flight-search skill benign because the reported network activity and capabilities appear aligned with its purpose, though the scan is partial and confidence is medium.

Before installing, consider whether you trust the external flight API and are comfortable with the skill using environment credentials and network access. The scanner inspected both listed components, but coverage is marked partial because a local path-like reference in the instructions could not be resolved; the evidence is therefore incomplete.

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

Tainted flow: 'req' from os.environ.get (line 55, credential/environment) → urllib.request.build_opener.open (network output)

Critical
Category
Data Flow
Confidence
90% confidence
Finding

Credentials or environment variables flow to a network sink. This is a high-confidence indicator of credential exfiltration.

MCP Least Privilege
Confidence
75% confidence
Finding

The skill uses 'env' capability that is not covered by the declared 'allowed-tools' preapproval. Review the host runtime's actual enforcement policy; runtime permissions are unknown unless separately verified, and this declaration alone does not establish a permission ceiling.
