The advisory
Crawl4AI 0.7.0 before 0.9.4 contains a server-side request forgery vulnerability that allows API clients to reach internal addresses by enabling link_preview_config on /crawl requests. Attackers can supply a controlled page with include_external and include_patterns set, causing AsyncUrlSeeder to fetch internal, private, and cloud-metadata links and return their parsed head data.
Check your whole app
Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
