Security audit

Brand DNA Extractor

Security checks for vulnerabilities and agentic risk

Overview

The skill’s website scraping and AI brand analysis are mostly disclosed, but it recommends exposing a broad Supabase service-role key and lacks tight privacy scoping for externally processed website content.

Install only in an isolated environment with pinned dependencies. Use the skill only on public or authorized sites, assume representative images may be sent to Gemini or OpenAI, and avoid providing a Supabase service-role key; prefer storage disabled or a narrowly scoped cache-only credential/RPC.

A.I.G

Vulnerability Patterns

Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The top-level skill description does not clearly warn that the skill will scrape arbitrary websites, optionally crawl subpages, and transmit extracted images/content to external AI providers and optional Supabase storage. This can mislead users into providing URLs containing sensitive, internal, or legally restricted content, creating privacy, confidentiality, and compliance risks through unexpected data egress.
