E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
These URLs include direct remote ZIP links (example.com/plugin.zip) and a blueprint URL that pulls a ZIP from an untrusted domain (playground.wordpress.net/?blueprint-url=https://example.com/bundle.zip), which can be used to deliver arbitrary/malicious code.
Low
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
SKILL.md describes a WordPress Playground Blueprint format where the required runtime workflow executes user-authored blueprint JSON and can ingest arbitrary free-text/code via step fields like `runPHP.code`, `runSql.sql.contents`, and file contents in `writeFile.data`/`writeFiles.filesTree`, i.e., outsider-authored text is directly provided to runtime execution without first selecting a specific trusted item.
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 blueprint examples include runtime-fetchable code resources (plugin/theme bundles and git repos) that will be fetched and executed by the Playground (e.g. https://example.com/plugin.zip, https://github.com/WordPress/gutenberg, https://github.com/user/repo, and the playground URL referencing https://example.com/bundle.zip), which is high-confidence evidence of external runtime dependencies that can execute remote code.
