Treadmill Buying Consultant

Security checks for vulnerabilities and agentic risk

Overview

This is an instruction-only treadmill shopping guide, and the scanner concerns were only table spacing after inspection.

Installers should understand that the skill may ask for height, weight, joint-health context, city/country, and room details to make buying recommendations. No code execution or credential access is present, but users should still avoid sharing more personal detail than needed.

A.I.G

Vulnerability Patterns

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
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Whitespace Padding

Medium

Category: Prompt Injection
Content: ### R1 — Technical Specifications | Spec | What It Measures | Standard Range | Why It Matters | Listing Label | | --------------------- | ------------------------------------- | ------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------- | --------------------------------------------------------- | | Motor Power (CHP) | Continuous usable power output | 1.5–4.0+ CHP | Determines long-term motor endurance under load; peak HP is a misleading marketing metric | "CHP", "continuous duty HP", "motor HP" | | Belt Size | Running surface (W × L) | 18"–22" wide, 50"–62" long | Determines if stride fits safely; inadequate length causes shortened stride and injury risk | "running surface", "belt size", "tread belt" |
Confidence: 70% confidence
Finding: Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

Whitespace Padding

Medium

Category: Prompt Injection
Content: ### R2 — Factors That Determine Required Specs | Factor | Affected Spec(s) | Direction of Effect | | ---------------------------------- | ----------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------- | | User body weight | Weight capacity, motor CHP | Higher weight → higher capacity buffer needed; heavier users stress motors more | | User height | Belt length | Taller users (>6 ft / 183 cm) need belts ≥ 60" long for full stride |
