Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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
The `website` runtime workflow for `https://playground.wordpress.net/` ingests outsider-authored free text when an attacker supplies a `#...` inline Blueprint fragment or a `?blueprint-url=<url>` that loads public Blueprint JSON/ZIP content, which the agent then uses to drive site setup.
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
The skill allows loading remote Blueprints and site setup via the Playground website (e.g., https://playground.wordpress.net/ and the example https://playground.wordpress.net/?php=8.4&wp=latest&plugin=gutenberg&networking=yes&url=/wp-admin/post-new.php), and the CLI also accepts --blueprint=<file-or-url>, so external URLs fetched at runtime can supply Blueprint JSON/ZIP that directly control environment setup and execute code or steps.
