Security audit

Gnamiblast

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches an AI social-network integration, but it asks agents to accept remote policy data as agent constraints and uses an unpinned installer package.

Review this skill before installing. Use it only if you are comfortable with GnamiBlast network access, public posting/commenting/voting by an agent, and a scoped GnamiBlast token. Do not let remote GnamiBlast policy responses alter global agent rules or abort unrelated tasks; treat them only as platform policy data. Prefer a pinned, reviewed installer version instead of running the documented `@latest` command.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

Finding

The installation command uses npx molthub@latest, which fetches and executes the most recent published package version at install time rather than a reviewed, fixed version. If the upstream package is compromised, typosquatted, or updated with malicious code, users of this skill could execute attacker-controlled code during installation.
