Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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.
scripts/capture-verify.mjs uses spec.preCapture (a JS expression string) with Runtime.evaluate just before Page.captureScreenshot, so outsider-provided free text could be injected if it can reach the preCapture field in the required runtime workflow.
