Stock Browser Fetcher

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow browser-based A-share market data fetcher with no bundled executable code, persistence, credential use, or hidden behavior, though users should consider site terms before scraping.

Install only if you intend to fetch China A-share market data through browser automation. Check Eastmoney and Sina Finance terms, keep request volume modest, and prefer official or licensed APIs where required.

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill explicitly advertises bypassing anti-scraping mechanisms on third-party financial sites, but the description does not warn users about the legal, contractual, operational, and account/IP-blocking risks of doing so. In a browser-automation skill targeting live financial websites, omission of this warning increases the chance of unsafe or policy-violating use and can expose operators to service abuse complaints or access restrictions.

Natural-Language Policy Violations

Low
Category

Confidence
78% confidence
Finding

The natural-language description is entirely in Chinese and the skill is narrowly framed around A-share market data sources, but it does not explicitly state that it is a China-market-specific skill or offer a language/locale choice. The policy calls for flagging language or locale constraints when they are imposed without opt-in or clear justification.
