Security audit

Google Sheets for Shopify via Agiexa

Security checks for vulnerabilities and agentic risk

Overview

This skill offers information and an optional waitlist for a future integration, although its feature description and privacy wording need clarification.

Installing this package does not enable Google Sheets or Shopify automation. Joining the waitlist sends Agiexa your email, role, and any optional link or message you provide. Omit sensitive information; the privacy statement should explicitly acknowledge these optional fields. Publisher security claims were not independently verified.

A.I.G

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only submits a waitlist signup. It does not connect to Google Sheets or Shopify, export store data, read supplier sheets, or implement the advertised tools and triggers. Although the destination is the declared provider, waitlist enrollment is a materially different primary purpose and is not described as part of the skill. The submitted contact and store values are fixed placeholders, not data collected from the user's environment.

External Transmission

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.

The manifest advertises operational Google Sheets tools, but task requests are redirected to a prelaunch waitlist.

Medium
Category
Excessive Agency
Confidence
98% confidence
Finding

The manifest at L003 describes exporting Shopify data and reading supplier sheets through 50 tools and 16 triggers. However, L071 explicitly instructs the agent not to perform those tasks and instead promote a future launch; the provided executable request submits contact details to a waitlist rather than performing a Sheets operation.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

> Help me configure a Google Sheets monitoring workflow for my Shopify business workbook. Monitor the specified sheet or cell range for relevant changes, such as new product rows, modified inventory quantities, updated campaign metrics, or changes to important summary values. When a change occurs, validate the affected data, recalculate dependent summaries where appropriate, and flag issues such as low stock, duplicate SKUs, missing fields, or unusually high advertising costs. Avoid repeated processing and preserve manually maintained fields. Explain which trigger best matches the requested change and which downstream actions require a separate workflow. Do not send external messages or modify unrelated records without approval.

The privacy assurance contradicts the submission of a user's store URL.

Low
Category
Excessive Agency
Confidence
96% confidence
Finding

The assurance that nothing about the user's store is sent contradicts the optional submission of their Shopify store URL. This can mislead users about the disclosure of a business identifier, although explicit consent, user-supplied values, and an optional URL substantially limit the risk.
