Security checks for vulnerabilities and agentic risk

Overview

This image-review skill also exposes recurring paid monitoring and can spend account credits without fresh approval.

Prefer a corrected package that enforces image-only commands and approval before spending. Omitting --confirm does not reliably prevent charges. If proceeding, set billing to ask every time and separately approve any recurring collection, which can continue consuming credits after the conversation.

Recurring collection and subsequent credit consumption can continue beyond the current task without the separate confirmation promised by the Skill.

Finding

Deepdive's quote-only default is overridden by shared automatic confirmation

Content
View full analysis

Impact

A deepdive invocation documented as non-charging by default can generate and charge for a report. In the missing-product fallback, the output can additionally claim that analysis was reduced to quotation and no credits were charged.

MCP Tool Poisoning
Confidence
99% confidence
Finding

The image-only skill includes conflicting general-purpose instructions for paid analysis, recurring collection, and caller-selected operations workflows. The final fixed-entry restriction mitigates this, but earlier claims that this package is unrestricted and should sometimes execute without confirmation create an actionable scope and authorization ambiguity.

Confidence

Finding

Persistent watches introduce ongoing financial and account-state effects beyond a bounded image audit. Explicit pricing and consent requirements substantially reduce the risk, but the watch instructions still conflict with the final image-only execution boundary.

Category
MCP Tool Poisoning
Confidence
95% confidence
Finding

This overlaps the persistent-watch scope issue: an image-review skill instructs the agent how to create and manage recurring billable services. The documented consent checks reduce the likelihood of unauthorized charges, but contradictory scope instructions leave an avoidable execution path outside the advertised boundary.

Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The supplied invocation requests a category-level ranking and does not identify a main ASIN, authorized competitor pages, or an image-audit task. Although review feedback is relevant to the declared purpose, generating a Kitchen leaderboard by negative-feedback rate is a distinct, undeclared capability. The script implementation is not supplied, so additional effects cannot be established.

Confidence

Finding

The supplied commands concern watch configuration and service costs, not comparison of product images, visible information, or review feedback. These capabilities are not disclosed in the declared purpose, and the chunk provides no connection establishing them as supporting implementation details of image auditing. The snippet does not establish that monitoring is activated or that any explicitly excluded advertising, inventory, ordering, or publishing activity occurs.

Finding

The competitor-binding instructions state that adding a competitor starts weekly collection, but do not require separate recurring-charge consent at that step. Authorization for a one-time comparison does not establish authorization for ongoing competitor collection, despite the broader scheduling safeguards elsewhere.

Confidence

Finding

Weekly collection creates continuing financial obligations beyond the image comparison requested by this skill. Instructions to use manual collection without recurring authorization are protective, but the package still mixes recurring scheduling with an image-only boundary.

Confidence

Finding

Watch creation and resumption can establish recurring charges unrelated to the declared image audit. The skill requires explicit price acceptance, so this is a conflicting-scope exposure rather than demonstrated automatic enrollment.

Confidence

Finding

The supplied commands concern monitoring-service quotes and watch listings rather than image information review or photography guidance. These are undeclared capabilities, and the chunk provides no connection establishing them as supporting steps for the stated image-review workflow. The visible code does not establish that monitoring is enabled or modified.

Confidence
80% confidence
Finding

The chunk exposes watch-monitoring and historical reporting operations rather than explicitly comparing product images or producing photography guidance. Nothing supplied connects these watch operations to image-information review, so they appear to introduce an undeclared capability. However, the underlying script and returned data are not shown; the evidence does not establish sales forecasting, inventory access, order handling, advertising, or automatic publishing.

Finding

The supplied entry point explicitly selects an alerts operation, which does not match the stated image-information review workflow. The implementation of scripts/ari.py is not provided, so the specific alert behavior, resources accessed, and side effects cannot be established.

Turns an unanswered quote into a later paid execution without renewed user authorization.

High
Category
Prompt Injection
Confidence
99% confidence
Finding

The skill explicitly treats an unanswered earlier quote as a reason to generate a report in a later conversation, potentially charging through automatic confirmation. Silence is not authorization, and an idle product record does not establish current intent or acceptance of the current price.

The skill exposes persistent, billable product-monitoring management unrelated to a bounded image comparison.

High
Category
Excessive Agency
Confidence
97% confidence
Finding

The monitoring section exposes persistent account mutations and recurring charges outside the bounded image-review purpose. Its explicit quote, ownership, deletion-target, and consent safeguards reduce severity, but do not resolve the contradictory specialized execution scope.

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

Confidence

Finding

run_analysis changes confirm to True based on a server-provided autoConfirm value, allowing chargeable analysis without the explicit flag promised by the module. cmd_voc has an equivalent bypass that can also submit paid collection; deepdive inherits run_analysis behavior, although actual CLI reachability depends on the unseen command allowlist.
