Security checks for vulnerabilities and agentic risk

Overview

This title-advice skill includes broader account tools and confirmation gaps that could cause unexpected or recurring charges.

Prefer a corrected version that enforces title-only access and fixes preview charging. If using this version, configure ARI to ask before every charge, explicitly choose manual collection for one-time work, and review active schedules and competitor monitoring. Omitting --confirm does not reliably prevent spending.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Finding

Read-only deepdive fallback can execute paid analysis

Content
View full analysis

Impact

A user following the documented read-only/default workflow can incur an analysis charge. When the product is absent and --confirm was supplied, the command can additionally claim that analysis was downgraded to quote-only and no credits were charged despite reaching the paid execution path.

Finding

Recurring paid collection can be enabled without an executable confirmation gate

Content
View full analysis

Impact

These directly callable paths can start recurring credit deductions before the user has approved the recurring cost. Competitor deductions are conditional on the parent product remaining monitored.

MCP Tool Poisoning
Confidence
99% confidence
Finding

The title-only skill contains actionable instructions for unrelated paid reports, account settings, recurring collection, and generic operations. Its final title-only restriction mitigates this but conflicts with earlier mandatory workflows, creating a credible route to out-of-scope actions and credit spending; the underlying code was not provided for verification.

Finding

This is another instance of monitoring mutations exceeding the advertised title-only scope. Creating or resuming watches can authorize recurring charges, although the required quote, explicit agreement, and accepted-price parameter are meaningful safeguards.

Finding

Creating and managing recurring watches exceeds title diagnosis and can establish continuing financial obligations. Explicit price confirmation and ownership checks substantially reduce the danger, but these capabilities remain exposed through contradictory instructions in a narrowly advertised skill.

Confidence

Finding

This duplicates the out-of-scope watch-management issue: the skill exposes persistent monitoring and state-changing management commands despite its title-only contract. Required user authorization reduces the likelihood of unauthorized recurring charges, but conflicting scope instructions still create avoidable authority expansion.

Finding

Competitor association is described as automatically enabling weekly collection, which is a persistent side effect outside title diagnosis. Unlike the detailed watch flow, this instruction does not locally require disclosure and explicit acceptance of the recurring collection cost.

Finding

Recurring review collection is outside title diagnosis, and new-product collection defaults to weekly billing. The instructions require manual scheduling when recurring collection is not authorized, but relying on an agent to override a billable default creates a preventable financial-risk path.

Confidence
93% confidence
Finding

The supplied commands expose monitoring and historical-reporting capabilities that are not declared in the title-diagnosis description. The chunk shows no title analysis or connection between these watch outputs and product-title recommendations, so these operations are not established as supporting implementation details. It does not show watch creation, advertising, or automatic publishing.

Confidence

Finding

The supplied command requests a category leaderboard based on negative-review rate, a distinct analytical output not declared in the title-diagnosis purpose. No title analysis or connection to title recommendations is shown. The underlying script is unavailable, so this assessment does not infer additional API access, publishing, or other side effects.

Finding

The supplied commands expose watch-related functionality rather than product-title diagnosis or recommendations. Recurring-watch pricing and watch listing are not declared capabilities, and the chunk provides no connection establishing them as supporting steps for title diagnosis. It does not demonstrate watch creation, automatic publishing, or advertising.

Confidence

Finding

The supplied commands concern monitoring features and their pricing, neither of which is declared as part of title diagnosis or recommendations. Using the ARI API is consistent with the description, but these particular capabilities are not evidently supporting implementation details for the stated task. The snippet does not show watch creation, modification, or automatic publishing.

Finding

The generic operations section describes broad audits and says this package is unrestricted, contradicting the final listing/title-only entry point. This creates scope ambiguity that could lead to unrelated analysis and spending, although the supplied document requires explicit authorization for operations charges.

Confidence

Finding

The concrete concern is not merely that alerts exist: the workflow mandates fetching and proactively discussing account-wide alerts at session start. This accesses information about potentially unrelated products without a title-analysis need, although no external disclosure or automatic paid reply generation is shown.

Content

No source excerpt is available for this finding.

An unanswered quote is used as a pretext to initiate paid report generation in a later conversation.

High
Category
Prompt Injection
Confidence
99% confidence
Finding

The instruction treats an unanswered earlier quote as grounds to generate a report during a later conversation. An idle product is not evidence of current spending authorization, and server auto-confirmation can turn that inference into a real credit deduction.

Content

Paid analysis can execute without the explicit --confirm flag promised by the module documentation.

Category
Excessive Agency
Confidence
99% confidence
Finding

run_analysis changes confirm from false to true based on a server-supplied autoConfirm value, allowing a nominal preview invocation to spend credits. This contradicts the explicit-confirmation contract and also affects callers such as deepdive; exposure depends on which commands the package whitelist permits.
