Medium

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: 0.90). The skill's SKILL.md shows runtime fetching and parsing of public, user-served content that the agent must interpret and act on—e.g., wfsUtils.getCapabilities("https://geobretagne.fr/geoserver/ows") to discover featureTypes, KMLLayer loading the USGS KML feed, CatalogLayer portalItem lookups, and MediaLayer image/video URLs—so untrusted third-party data can directly influence layer creation and subsequent actions.

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: 1.00). The skill loads and executes remote JavaScript from the ArcGIS CDN at runtime (e.g., https://js.arcgis.com/5.0/ and https://js.arcgis.com/calcite-components/3.3.3/calcite.esm.js), which are required dependencies and cause remote code to be fetched and executed.
