Security
2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
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.
Why it was flagged
Third-party content exposure detected (high risk: 1.00). The skill explicitly ingests and acts on external, potentially untrusted content at runtime — e.g., Server Tools (webhooks) that call arbitrary external URLs (see "Server Tools (Webhooks)" and get_weather example), the Knowledge Base & RAG flow that retrieves uploaded/public documents during conversations ("Knowledge Base & RAG"), and MCP Tools that connect to third‑party MCP servers — all of which the agent reads/interprets and can change tool calls or responses.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
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.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill includes explicit runtime MCP server endpoints (e.g., "server_url": "https://my-mcp.workers.dev/mcp" and "https://your-mcp-server.com") which ElevenLabs calls via JSON‑RPC at runtime to invoke tools — these external servers execute code and return responses that directly affect agent behavior/prompts, so they are high-risk runtime dependencies.
