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: 0.90). The skill's SKILL.md shows runtime fetching of public third‑party content (esriRequest in fetchTile to tile URL templates such as https://tile.opentopomap.org/{z}/{x}/{y}.png and an ESM import of the LERC decoder from https://cdn.jsdelivr.net/npm/lerc@4.0.4/+esm), so it ingests untrusted external data and third‑party code that can influence runtime 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: 0.90). The skill loads and executes remote JavaScript at runtime (required for operation) from https://cdn.jsdelivr.net/npm/lerc@4.0.4/+esm (Lerc decoder) and https://js.arcgis.com/4.34/, so these external URLs execute remote code used by the skill.
