Security audit

Seo Content Brief

Security checks for vulnerabilities and agentic risk

Overview

The skill's SEO workflow is mostly coherent, but its setup instructions ask users to execute a mutable remote installer and optional unpinned installs, which need careful review before use.

Review the installer before running it, prefer a manual or pinned installation path with independent checksum or signature verification, and avoid the optional related-skill `npx` installs unless you can pin and audit the exact versions. Expect the skill to send search queries and extracted URLs through inference.sh-backed apps as part of normal SEO research.

  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • 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
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remotely fetched script directly into sh executes untrusted network content immediately, creating a classic supply-chain and remote code execution risk. Even with accompanying claims about checksum verification, the dangerous behavior occurs before the user can independently inspect or validate the script, and the SEO/content-brief context does not justify such a risky install pattern.

Finding

This markdown file declares many trigger phrases in the description, including generic terms like "content brief," "keyword research," "content strategy," and "content planning." These are broad enough to match ordinary user requests outside this specific skill, and the file does not provide exclusion conditions or tighter activation constraints.

Finding

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Finding

The manifest describes the skill as focused on SEO content briefs, keyword research, SERP analysis, and content structure. The included workflow also instructs users to generate an infographic image, which is a content asset creation capability rather than a core content-briefing activity.
