2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.90). The skill explicitly lists and deploys templates from a public Template Marketplace (e.g., mcp__flow-nexus__neural_list_templates and mcp__flow-nexus__neural_deploy_template and the https://flow-nexus.ruv.io/templates links in SKILL.md), which are third‑party/user-published resources the agent reads and can act on, so untrusted content could influence tool use or follow-up actions.
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Potentially malicious external URL detected (high risk: 0.90). The skill's prerequisites invoke "npx flow-nexus@latest" (which fetches and executes remote npm package code at runtime) as a required dependency, so the npx-installed flow-nexus package is a runtime external code-execution risk (also associated with https://flow-nexus.ruv.io for registration/docs).
