• Version: 1.0.0

Overview

This JD Gold assistant has coherent financial features, but it also includes account-token handling, background simulated trading, and an unsafe self-update path that should be reviewed before installation.

Install only if you trust the publisher and are comfortable granting JD account authorization to this skill. Before enabling autotrade, confirm the exact schedule, spending limits, token lifetime, and a real removal procedure that deletes the LaunchAgent plist. Prefer not to use it on shared machines or environments where other users can read local files or set environment variables.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs
• System Persistence: Installs backdoors, hooks, services, or scheduled tasks that survive the run
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection

Missing User Warnings

High

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The automatic托管 feature can continue operating after authorization and place simulated orders on a schedule, yet this persistence and autonomy is not warned prominently at the top-level description. Because the same skill also includes login, local task installation, and background execution instructions, insufficient upfront disclosure makes unintended long-running automation significantly more dangerous.

Credential Access

High

• Category: Privilege Escalation
• Confidence: 70% confidence

Finding

The code explicitly documents that on non-macOS/non-Windows platforms secure_store may fall back to a 0o600 plaintext file for storing the OAuth access token. On shared or compromised hosts, local plaintext token storage increases the chance of credential theft and unauthorized use of the user's financial account session, which is more sensitive in a gold trading skill than in a low-risk app.

• Category: Privilege Escalation

Finding

This comment marks the plaintext fallback backend for secrets, and the implementation below stores credentials in cleartext with only filesystem permissions as protection. In a finance-related skill handling access tokens, plaintext local storage significantly increases exposure if the host is shared, backed up, malware-infected, or permissions are weaker than assumed.

Credential Access

High

• Category: Privilege Escalation
• Confidence: 95% confidence

Finding

The public save_secret API silently falls back to _file_save on any platform/backend exception, causing secrets to be persisted in plaintext without informing the caller. That hidden downgrade weakens confidentiality guarantees and is particularly risky for tokens associated with trading or account features in this skill context.

Credential Access

High

• Category: Privilege Escalation
• Confidence: 92% confidence

Finding

The load path also silently falls through to plaintext file reads when secure backends fail or return nothing, normalizing insecure storage and making it hard for callers to distinguish secure from insecure sources. This can prolong secret exposure because the application continues operating without surfacing that credentials are coming from an unprotected file.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 94% confidence

Finding

The skill describes capabilities that require shell, file, network, environment access, but it does not declare an explicit tool/permission scope. This creates an over-privileged and non-transparent execution model where a host agent may grant broader access than users or reviewers expect, increasing the blast radius of any prompt injection, logic bug, or malicious update path.
