CVE-2026-57572Public exploitNetwork attack vector

Unauthenticated RCE via Chromium launch-argument injection

Published Jul 6, 2026 · Updated Jul 6, 2026

Argument injection in Crawl4AI before 0.9.0 allows remote attackers to execute commands through the unauthenticated Docker API. The server passes request-supplied browser_config.extra_args into Chromium, allowing launch switches plus --no-zygote to replace a child-process command. Default deployments require no authentication, and execution runs as the container runtime user with access to application data, mounted secrets, environment variables, and tokens.
