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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
