AI Opportunity Navigator

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently helps compare public freelance opportunity pages against a user profile, with disclosed local filtering and no evidence of hidden persistence, credential use, applications, purchases, or data exfiltration.

Before installing, be aware that live verification will contact public opportunity websites and that the optional human review/payment flow is separate from the free skill experience. Do not provide credentials, identity documents, payment details, or submit applications through the skill; treat job availability, approval, and earnings as unverified until confirmed on the original sites.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
88% confidence
Finding

The skill instructs the agent to read a local file and run a shell command (python3 scripts/match.py --profile - --live) but does not declare any tool scope such as permissions or allowed-tools. That creates a least-privilege gap: a host may permit broader file or shell access than the skill actually needs, increasing the chance of unintended command execution or file access if the skill or adjacent content is modified or abused.

Intent-Code Divergence

Medium

Not specified by scanner
Confidence
91% confidence
Finding

The module docstring says 'No credentials, telemetry or personal-data transmission,' which reads as a strong no-transmission claim. In live mode, the code performs external HTTP requests with curl to each opportunity source URL; while it does avoid sending the user profile, it still transmits network metadata and contradicts an absolute 'no ... transmission' statement.

subprocess module call

Confidence
70% confidence
Finding

subprocess module calls execute external commands. Without careful input validation, this enables command injection.
