Security checks for vulnerabilities and agentic risk

Overview

This snapshot tracker also exposes unrelated spending controls and paid services, with conflicting information about recurring costs.

Prefer a corrected watch-only package before connecting your ARI key. Verify recurring refresh prices and require confirmation before spending credits; this build also exposes account-wide spending settings and unrelated paid commands.

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

Remote auto-confirm policy can turn an unconfirmed invocation into paid execution

Content
View full analysis

Impact

Account credits can be consumed before the caller approves the current price. The expenditure is conditional on the returned policy and available balance; this is not evidence of arbitrary payment-card charges.

Description-Behavior Mismatch

Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The watch digest and series commands align with the declared purpose, but substantial executable functionality exceeds it. run_analysis() invokes paid analysis endpoints; cmd_voc() combines collection and AI report generation; both support server-authorized automatic confirmation. Collection, schedule, watch, and competitor commands can initiate new data acquisition or recurring charged activity. These are material capabilities, not supporting details of a read-only snapshot summary. main() exposes these commands unless an external skill-defaults.json restricts them. That file is not supplied, and allowed_commands() defaults to unrestricted operation when its configuration is missing or invalid, so the supplied code does not establish the declared limitation. No hourly monitoring, inventory management, order processing, or automatic repricing is demonstrated.

Confidence
92% confidence
Finding

Digest and event retrieval could support the declared snapshot-tracking purpose, but scheduled watch creation and lifecycle management extend beyond the stated summary-only scope. Weekly scheduling does not violate the explicit exclusion of hourly monitoring; the mismatch is the undeclared watch-management capability. The chunk does not establish paid LLM use, real-time claims, sales prediction, or inventory, advertising, order, or repricing operations.

Finding

Digest retrieval is compatible with snapshot-based reporting, but scheduled watch creation and lifecycle management materially expand the declared summary-only scope. Weekly scheduling does not violate the specific exclusion of hourly monitoring. The snippet does not establish paid LLM use, real-time claims, sales prediction, or inventory, advertising, order, or repricing operations.

Confidence
91% confidence
Finding

Digest and event retrieval could support the declared snapshot-tracking purpose. However, creating and managing scheduled watches adds operational capabilities beyond summarizing already-saved snapshots, and those capabilities are not disclosed in the description. The weekly schedule does not contradict the exclusion of hourly monitoring. The chunk provides no evidence of paid LLM use, real-time price claims, sales or ranking predictions, or inventory, advertising, order, or repricing operations.

Confidence

Finding

Digest and event retrieval plausibly support the declared snapshot-tracking purpose. However, creating a recurring watch and changing or deleting watches introduce operational capabilities beyond the stated read-and-summarize scope. Weekly scheduling does not violate the explicit exclusion of hourly monitoring. The underlying Python implementation is not supplied, so the snippet does not establish paid LLM use, real-time claims, sales prediction, or inventory, advertising, order, or repricing operations.

Finding

Digest and event retrieval plausibly support the declared snapshot-tracking purpose. However, creating, pausing, resuming, and deleting scheduled watches introduces an operational monitoring capability that the description does not disclose. Weekly scheduling does not contradict the explicit exclusion of hourly monitoring. The supplied chunk contains command examples rather than implementation, so it does not establish actual API access, paid LLM use, real-time claims, or other excluded behavior.

Changing account-wide automatic spending confirmation is unrelated to price/BSR snapshot tracking.

High
Category
Excessive Agency
Confidence
98% confidence
Finding

cmd_autoconfirm can change account-wide automatic-spending policy through an authenticated PUT, despite this skill only promising snapshot tracking. If reachable, an agent can weaken confirmation requirements beyond the current task; the external command allowlist may restrict access, but its contents are not supplied and its implementation fails open.

Content

No source excerpt is available for this finding.

The snapshot-only skill can initiate fresh review collection and configure recurring paid collection.

High
Category
Excessive Agency
Confidence
96% confidence
Finding

The implementation can submit fresh review collection, enable recurring paid collection, and add competitors that are automatically collected weekly. These capabilities exceed saved-snapshot tracking; collection requires --confirm, but schedule and competitor mutations lack an equivalent local spending-confirmation gate.

Content

Paid AI-analysis execution contradicts the manifest's explicit prohibition on paid LLM calls.

High
Category
Excessive Agency
Confidence
97% confidence
Finding

run_analysis can invoke paid AI endpoints, directly conflicting with this skill's stated prohibition on paid LLM calls. CLI reachability depends on the unprovided skill-defaults.json, but the supplied implementation retains these commands and allows them when the allowlist is missing or invalid.

Content

No source excerpt is available for this finding.

Server-driven automatic confirmation contradicts the documented requirement for an explicit --confirm flag.

High
Category
Excessive Agency
Confidence
100% confidence
Finding

A sufficient balance and truthy server autoConfirm value convert confirm=False into confirm=True, allowing paid analysis without the documented explicit --confirm flag. This also affects callers such as deepdive that expect an unconfirmed invocation to remain a quote; later charge reporting does not provide prior consent.
