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). This skill's documentation and examples (e.g., SKILL.md and references/github-auto-updates.md) explicitly instruct the agent/plugin to fetch and parse remote update metadata and packages from public URLs/GitHub (e.g., wp_remote_get(MY_PLUGIN_UPDATE_URL) and PucFactory::buildUpdateChecker('https://github.com/...')), which are untrusted third‑party sources and can materially change behavior by supplying updates or instructions at runtime.
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). Flagged because the skill includes runtime auto-update logic that queries and downloads plugin packages from GitHub (e.g., https://github.com/yourusername/your-plugin/) and relies on the Plugin Update Checker library (https://github.com/YahnisElsts/plugin-update-checker), which at runtime can fetch and install remote ZIPs containing executable plugin code.
