MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.80). The skill's create-theme workflow explicitly instructs the agent to "read each path with the Read tool" for image inputs that can be "paths or URLs to slide screenshots, mood-board images, brand assets" (rules/create-theme.md Step 2), which requires ingesting potentially untrusted public URLs and then extracting palette/fonts/typography that will drive subsequent theme generation and edits—so third‑party content can materially influence actions.
