Stockmarket

Security checks for vulnerabilities and agentic risk

Overview

This appears to be a straightforward Alpha Vantage market-data helper, with minor caution around broad activation phrases and API-key handling.

Install only if you are comfortable sending market-data queries and an Alpha Vantage API key to Alpha Vantage. Prefer setting ALPHA_VANTAGE_KEY over passing --key on the command line, and be aware the broad triggers may cause the skill to be considered for generic stock-market requests.

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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list is broad and includes generic financial phrases like 'stock market', 'stock price', and 'market data', which can cause the skill to activate for many ordinary finance-related requests. Unintended activation is risky because the skill has Bash permission and may cause external API calls or command execution when a user did not explicitly intend to use this specific skill.

Missing User Warnings

Category
Not specified by scanner
Confidence
84% confidence
Finding

This code file sends command inputs such as stock symbols, search keywords, topics, and tickers to Alpha Vantage over HTTP(S). Although the module docstring names the API, there is no runtime warning, confirmation, or explicit disclosure that user-provided inputs and the API key from the environment may be transmitted to a third-party service.
