Security checks for vulnerabilities and agentic risk

Overview

This feature-ranking skill exposes broader paid services and can spend account credits without clear approval.

Review before installing. Require approval of each quoted cost, disable account auto-confirmation, and separately approve recurring collection. Request a corrected package that enforces its advertised feature-ranking scope and fixes the quote-only fallback; conversation instructions alone do not reliably enforce these limits.

Finding

Quote-only deepdive can silently become a paid analysis

Content
View full analysis

Impact

Account credits can be consumed and a report generated when the documented command behavior promises only a quote. For a missing main subscription, the subsequent productNote can also incorrectly claim that no credits were deducted.

Finding

Recurring paid collection changes lack an enforceable confirmation gate

Content
View full analysis

Impact

A direct helper invocation can enable continuing credit consumption without first presenting and confirming recurring costs. Approval for a one-time analysis or competitor comparison does not establish approval for ongoing collection.

Description-Behavior Mismatch

MCP Tool Poisoning
Confidence
98% confidence
Finding

The document mixes a feature-ranking-only entry point with general operational workflows and instructions to spend credits based on server-default auto-confirmation. The closing fixed-workflow and explicit-confirmation requirements mitigate the risk but conflict with earlier instructions, creating a plausible path to out-of-scope paid execution; the supplied material does not verify the additional code behaviors alleged by the scanner.

Category
MCP Tool Poisoning
Confidence
95% confidence
Finding

The supplied commands concern watch services and their pricing, rather than analyzing reviews or ranking product-feature improvements. These are undeclared capabilities with no demonstrated supporting role in the stated purpose. The snippet does not establish sales forecasting, budget approval, or automatic purchasing, so those behaviors are not inferred.

Confidence

Finding

Recurring watch management and explicit price acceptance are substantive capabilities not disclosed by a description limited to product-feature prioritization. Although monitoring results could inform prioritization, configuring ongoing scheduled refreshes with price acceptance goes beyond merely retrieving supporting evidence. The chunk contains command examples rather than implementation, so it does not establish that charges or procurement actually occurred.

Finding

Recurring watch management and price acceptance are material capabilities not disclosed by the feature-prioritization description. Although monitoring could supply evidence for prioritization, these commands establish and manage ongoing activity rather than merely analyze evidence or rank features. The supplied chunk does not show the underlying CLI implementation, so it does not establish that charges occur, purchases are executed, or sales are forecast.

Finding

Retrieving monitoring data could support evidence-based feature prioritization, but managing recurring watches with price-acceptance parameters is a material additional capability not disclosed by the feature-ranking-only description. The excerpt contains no feature-ranking logic. It also does not establish sales forecasting, budget approval, or automatic procurement, so those behaviors are not attributed to it.

MCP Tool Poisoning
Confidence

Finding

Collecting reviews can support feature prioritization, but configuring recurring, potentially billable monitoring is a distinct operational capability not disclosed in the description. The snippet therefore extends beyond merely ranking product features. It does not establish automated purchasing, sales forecasting, or budget approval. This assessment is limited to the shown commands and comments; the implementation of scripts/ari.py was not supplied.

Confidence
87% confidence
Finding

The competitor workflow states that binding a competitor automatically enables weekly collection, without an accompanying step that obtains consent for that recurring collection. Authorization for a one-time comparison does not necessarily authorize an ongoing collection relationship or its possible charges; broader scheduling safeguards reduce but do not resolve this ambiguity.

Confidence

Finding

The supplied commands expose watch-service pricing and watch-listing functionality rather than analyzing review evidence or ranking product improvements. These are distinct capabilities not described in the declared purpose, and the snippet provides no connection establishing them as supporting implementation details. It does not show budget approval, purchasing, or modification of watches.

Treats an unanswered quotation as permission to generate a potentially paid report in a later conversation.

High
Category
Prompt Injection
Confidence
98% confidence
Finding

The instructions revive an unanswered quotation in a later conversation and direct immediate report generation if server auto-confirmation permits it. Silence is not authorization, and an idle product record does not prove current user intent to incur charges; the final explicit-confirmation requirement conflicts with this instruction rather than reliably preventing it.

Content

Paid analysis and collection can execute without the explicitly required --confirm flag.

High
Category
Excessive Agency
Confidence
99% confidence
Finding

run_analysis changes an absent confirmation into authorization based on a server-provided autoConfirm value, permitting credit-consuming requests without --confirm. cmd_voc similarly authorizes both collection and analysis, and deepdive can unexpectedly execute analysis despite describing its fallback as quote-only. This contradicts the CLI's explicit-confirmation contract and makes apparently noncommittal calls financially consequential.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
85% confidence
Finding

This entry endorses using the service's autoConfirm flag to bypass confirmation for credit-consuming operations, without establishing that the user previously authorized that spending. Free credits and balance checks reduce exposure but do not establish consent; this is a documented authorization-policy concern, not proof that the affected execution path exists in this specialized package.

Finding

The surrounding entry explicitly describes automatically collecting data, generating a report, and deducting credits without first presenting the price for approval. A service-controlled allowance for the first N paid operations has no stated monetary ceiling, so a request for analysis can cause unexpected credit consumption; post-operation charge disclosure does not prevent it.

This match concerns the same authorization issue: the service's boolean determines whether paid work proceeds, while the default first-N policy explicitly lacks an amount ceiling. Respecting user-set thresholds and insufficient-balance checks limits harm but does not substitute for initial spending authorization.

This is a duplicate match of the same documented spending-authorization weakness, not a separate exploit. Relying solely on autoConfirm can allow server policy to authorize deductions that the user has not explicitly approved, despite protections for explicit opt-outs and insufficient balances.

The workflow deliberately invokes a potentially charging command before obtaining a quote and says to discuss charges only after generation.
