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: 0.80). The skill explicitly loads third‑party map content (e.g., WebMap/WebScene via portalItem IDs from ArcGIS Online) and fetches arbitrary URLs via esriRequest and layer URLs (TileLayer, ElevationLayer), which are untrusted/user‑generated web resources that the agent is expected to ingest and which can materially change map layers, renderers, popups, and subsequent behavior.

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: 0.70). The skill requires CDN-hosted runtime assets that are fetched and executed in the browser—e.g. https://js.arcgis.com/5.0/, https://js.arcgis.com/5.0/map-components/, and https://js.arcgis.com/calcite-components/3.3.3/calcite.esm.js (plus the CSS at https://js.arcgis.com/5.0/esri/themes/light/main.css)—which are loaded at runtime and execute remote code the skill depends on.
