VOC洞察

Security checks for vulnerabilities and agentic risk

Overview

The skill can spend ARI credits without prior price approval, including through a command documented as quote-only by default.

Before requesting reports, set ARI to ask before every charge and verify that setting. Use the dedicated quote command for estimates, and avoid deepdive until its billing behavior is fixed. Approve recurring collection separately and review existing schedules.

Quote-only deepdive can execute paid analysis

View full analysis

Impact

A user or Agent expecting free data and an analysis quote can instead consume account credits and generate an archived report. In the missing-subscription fallback, the command can also state that no charge occurred despite having taken the paid path.

Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The security-relevant mismatch is not the additional features themselves but instructions allowing paid generation under server-selected first-use exemptions without a user-approved spending limit. Competitor binding also initiates weekly collection without a comparably explicit consent gate, potentially turning a one-time analysis into ongoing account activity.

Finding

Although Amazon product monitoring could support customer insights, persistent scheduled watches and explicit price acceptance are material capabilities not disclosed in the description. The supplied chunk manages monitoring lifecycles rather than performing the declared review analysis or generating recommendations. The underlying script is not provided, so actual billing and data-processing behavior cannot be verified.

Finding

Amazon ASIN data and monitoring outputs could support customer insights, but configuring persistent, price-bearing monitoring jobs is a material capability not disclosed in the description. The chunk focuses on watch lifecycle management rather than review analysis or listing recommendations. These are CLI examples; the underlying implementation and actual billing behavior are not shown.

Finding

The comparison workflow states that binding a competitor starts automatic weekly collection but does not explicitly require separate approval for that recurring activity. Consent to a one-time comparison price does not necessarily authorize persistent collection or any associated future charges.

Finding

Review monitoring can support customer insights, but creating, pausing, resuming, and deleting recurring watches with per-refresh pricing introduces operational and potentially billable capabilities not disclosed in the description. The visible chunk focuses on monitoring management rather than the declared review analysis and recommendation workflow. Because the underlying script is not supplied, actual billing execution and data access cannot be verified.

Finding

Review collection can support customer-insight analysis, but configuring persistent weekly monitoring with potential recurring charges is a material capability beyond the declared analysis and recommendation purpose. The supplied chunk exposes scheduling controls rather than insight generation. The underlying implementation and billing behavior are not shown, so this finding is limited to the commands and their accompanying comments.

Finding

The supplied commands concern watch management and cost estimation, capabilities not disclosed in the review-insights description. The chunk does not show review analysis or content recommendations, nor establish that these watch operations support those tasks. This assessment is limited to the visible commands; their underlying implementation is not supplied.

Finding

The supplied commands expose monitoring and pricing functionality that is not described in the declared review-insight and listing-optimization purpose. Although monitoring could support review analysis, this snippet does not establish that connection or perform the declared analysis. The visible commands only quote and list; they do not demonstrate enabling watches, making purchases, or changing settings.

Confidence

Finding

The supplied command explicitly selects an alerts operation, whereas the description declares customer-review insights and optimization recommendations, not alert functionality. This indicates a capability mismatch. Because the script implementation is absent, the evidence does not establish whether alerts are retrieved, created, or modified, or whether other side effects occur.

Paid analysis can execute without --confirm, contradicting the explicit-confirmation contract.

Category
Excessive Agency
Confidence
99% confidence
Finding

run_analysis converts an absent local confirmation into permission to spend credits based solely on the quote response's autoConfirm field. This contradicts the explicit-confirmation contract and can make analyze or deepdive charge unexpectedly; cmd_voc similarly extends remote approval to collection plus analysis.

Finding

The surrounding changelog describes allowing paid operations without price confirmation based on a server-provided autoConfirm flag, including for newly registered users. A service eligibility decision is not necessarily user authorization to spend credits; the documented default can consume account credits without informed approval, although runtime enforcement cannot be verified from this file alone.

Finding

The documented policy lets the first N paid generations proceed without an amount ceiling, while a request containing only an ASIN can trigger collection, analysis, and credit deductions. Honoring explicit user thresholds and checking the balance reduces exposure but does not establish spending consent for users who have never configured a threshold; reporting charges afterward does not prevent unwanted consumption.

This occurrence belongs to the same automatic-spending policy, not a separate exploit. Avoiding inference from explanatory text is sensible, but replacing that inference with exclusive reliance on a server boolean still leaves the documented absence of default user authorization and amount limits unresolved.

The changelog extends direct execution on autoConfirm=true to multiple analysis types, broadening the same spending-authorization weakness beyond the initial VOC workflow. Returning charges after execution provides visibility, but cannot prevent unintended deductions when no prior user budget or approval exists.
