Sina Finance ZYHub

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a read-only Sina Finance connector, but its setup fallback tells agents to run remote installer scripts directly in a shell without verification.

Install only if you trust OOMOL and the oo CLI supply chain. Before using the fallback setup commands, prefer an official installer page or verify the installer source, version, and integrity; avoid letting an agent run remote shell installers automatically. Expect ZYHub queries to go through your OOMOL-connected account.

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

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The skill instructs users to install software by piping a remotely fetched script directly into a shell, which creates a supply-chain and remote code execution risk if the host, network path, or served script is compromised. In this skill context, the danger is elevated because the instruction appears in an operational fallback path, making it more likely to be followed during troubleshooting without verification.

Finding

The description says to use this skill for "ANY Sina Finance ZYHub request" and "Whenever a task involves Sina Finance ZYHub," which is a very broad trigger without boundaries or exclusion conditions. In a markdown skill file, this can overlap with many ordinary finance-related requests and does not clarify when the skill should not activate.
