Weibo Search User Published Posts API

• Version: 1.0.0

Overview

This skill does only the documented Weibo API lookup, but it handles the API token in ways that can expose it in process listings and URL logs.

Install only if you are comfortable giving this skill a JustOneAPI token and having that token sent as a URL query parameter. Use a narrowly scoped token if available, avoid shared machines or verbose command/process logging, monitor usage, and rotate the token if it may have appeared in logs.

Vulnerability Patterns

• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands

Findings (6)

Credential Access

High

• Category: Privilege Escalation
• Confidence: 94% confidence

Finding

The presence of a required access token parameter indicates the skill handles credentials, and in this specific interface the credential is collected via a query parameter, increasing the chance of accidental exposure. The skill context makes this more dangerous because it is a third-party API integration for data retrieval, so user-supplied secrets may traverse multiple systems and be retained in request traces or service logs.

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.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 90% confidence

Finding

The skill invokes a network-capable helper (node .../bin/run.mjs) and uses an API token, but it does not declare any explicit tool scope such as permissions or allowed-tools. This creates a governance gap: an agent platform may permit broader tool usage than intended, reducing reviewability and increasing the chance of unintended outbound requests or misuse of the provided credential.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The skill requires an API access token to be sent as a URL query parameter, which is unsafe because query strings are commonly logged by clients, proxies, analytics systems, and server infrastructure. Even over HTTPS, the token may be exposed through logs, browser history, debugging tools, or downstream observability systems, creating a realistic credential leakage risk.

Vague Triggers

Low

• Category: Not specified by scanner
• Confidence: 83% confidence

Finding

This JSON file describes the skill and its purpose, but it does not specify any explicit invocation phrases, constraints, or exclusion conditions. For a manifest-style file, that can make activation behavior ambiguous because there is no clear boundary for when this skill should be selected versus similar search skills.
