Alibaba Cloud Data Analytics Dataanalysisgbi

• Outcome: Pass
• Latest audit: Sep 10, 2026 · 5:03 PM UTC
• Version: 1.0.3

Overview

This skill is a straightforward Alibaba Cloud DataAnalysisGBI helper; it uses expected cloud credentials and API metadata discovery, with no evidence of hidden persistence, exfiltration, or destructive automation.

Install only if you intend an agent to work with Alibaba Cloud DataAnalysisGBI. Use least-privilege Alibaba Cloud credentials, review any proposed Create/Update/Modify/Set action before it runs, and keep generated API-response artifacts in the documented output directory because they may contain operational details.

Vulnerability Patterns

• 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
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Taint Tracking: Direct Taint Flow, Variable-Mediated Taint Flow, Credential Exfiltration Chain
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands

Findings (9)

Tainted flow: 'timeout' from os.getenv (line 34, credential/environment) → urllib.request.urlopen (network output)

Critical

• Category: Data Flow
• Confidence: 90% confidence

Finding

Credentials or environment variables flow to a network sink. This is a high-confidence indicator of credential exfiltration.

python

def fetch_json(url: str, timeout: int) -> dict:
    req = urllib.request.Request(url, headers={"User-Agent": "codex-skill"})
    with urllib.request.urlopen(req, timeout=timeout) as resp:
        return json.loads(resp.read().decode("utf-8"))

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence

Finding

The declared purpose says the skill manages DataAnalysisGBI resources, but the documented executable path centers on metadata harvesting and local artifact generation instead of direct service operations. This mismatch is dangerous because it obscures the real behavior from reviewers and users, making it easier to justify unnecessary network access, credential use, and file creation under a misleading description.

Undeclared Tool Scope

Medium

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

Finding

The skill declares no explicit tool scope even though it clearly expects environment access, local file writes, and network/API usage. This weakens governance and reviewability because an agent may invoke broader capabilities than a user or platform policy expects, especially when cloud credentials and external API calls are involved.

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 60% confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Low

• Category: Not specified by scanner
• Confidence: 77% confidence

Finding

The skill advertises create, update, modify, and set operations against live cloud resources but does not prominently warn that these actions can change production state, incur cost, or disrupt service. In a cloud-management context, even ordinary mutations can have real operational impact if performed without explicit acknowledgement and safeguards.

Content

No source excerpt is available for this finding.

Missing User Warnings

Low

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

Finding

The skill instructs the agent to source Alibaba Cloud credentials from environment variables and a shared credentials file without an explicit warning about sensitive secret handling, minimization, or non-disclosure. In an agent setting, this increases the chance of overcollection, accidental logging, or use of credentials beyond what the user intended.
