Security checks for vulnerabilities and agentic risk

Overview

This skill appears non-malicious, but it exposes broader medication and health-content lookups than a simple price-comparison skill needs.

Review before installing. Use this only for public prescription price comparison, avoid precise coordinates unless needed, and do not rely on it for diagnosis, dosing, side effects, interactions, treatment choice, or medication changes.

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

Context-Inappropriate Capability

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The file documents access to diagnosis-adjacent condition content, dosing, side effects, interactions, and related medical guidance even though the skill description explicitly excludes diagnosis, dosing advice, and medication changes. In an agent setting, this creates a strong risk that the skill will be invoked to provide medical guidance beyond price comparison, which can lead to harmful or noncompliant health advice.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
90% confidence
Finding

The skill invokes a bundled shell script but does not declare any explicit tool scope or allowed-tools boundary. That makes the execution surface broader and less auditable, increasing the chance that an agent runtime could permit unintended shell access or command execution beyond the minimum needed for this task.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The file documents authenticated requests to an external API and describes sending request parameters, including optional location data, but provides no privacy notice or data-minimization guidance. In practice, this can lead agents to transmit user-provided sensitive contextual data to a third party without adequate disclosure or necessity review.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The endpoint reference exposes many GoodRx health-content capabilities unrelated to the skill's stated purpose of prescription price comparison, including articles, conditions, comparisons, and Q&A content. This unnecessary scope increases the chance the agent will retrieve or present medical information outside its intended boundary, creating prompt-scope drift and unsafe use of non-price content.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The price endpoint accepts precise latitude and longitude, plus ZIP code and state, but the documentation does not warn that this data may reveal a user's location to an external service. Because medication searches can imply sensitive health interests, combining them with precise location raises meaningful privacy risk.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
79% confidence
Finding

The reference says only that these are endpoints used by the workflow, but it does not define when the skill should or should not be invoked. Without explicit trigger and scope constraints, an orchestrating agent may overuse this skill for broader medication or health queries, increasing the likelihood of boundary violations.
