Mapbox Web Integration Patterns

• Outcome: Pass
• Latest audit: Sep 16, 2026 · 4:17 AM UTC
• Version: 1.0.0

Overview

This is a documentation-only Mapbox integration skill with expected token, CDN, and optional geolocation examples, not hidden or unsafe behavior.

This skill is reasonable to install for Mapbox integration help. Treat Mapbox browser tokens as public, restrict them in Mapbox settings, do not commit real .env files, pin library versions, and add clear user-facing consent and fallback behavior before using browser geolocation.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The document recommends using browser geolocation to center the map but does not mention privacy implications, user expectation management, or the need to clearly explain why location is being requested. While browsers enforce a permission prompt, omitting guidance on consent, minimization, and fallback behavior can lead downstream implementers to deploy location collection in a privacy-insensitive way.

Content

No source excerpt is available for this finding.

Missing User Warnings

Low

• Category: Not specified by scanner
• Confidence: 82% confidence

Finding

This markdown file includes guidance to use process.env.NEXT_PUBLIC_* for environment variables in client-side Next.js code. In Next.js, NEXT_PUBLIC_ values are exposed to the browser bundle, but the document does not warn readers not to place secrets or sensitive credentials there.

Content

No source excerpt is available for this finding.

Missing User Warnings

Low

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

This markdown file includes example usage that places a Mapbox access token directly in HTML attributes and environment-backed props, but the surrounding documentation provides no warning about handling API tokens safely. For markdown files, omissions of warnings about behaviors that could affect privacy or credentials handling fall under missing user warnings.
