CVE-2026-57572

Crawl4AI: Unauthenticated RCE via Chromium launch-argument injection in browser_config.extra_args

Published Jul 6, 2026 CVSS 3.1 · 10 Critical EPSS < 1% KEV · Not listed
Description
Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, the Docker API server accepted request-supplied browser_config.extra_args, which flowed into Chromium's launch arguments. An attacker could inject Chromium switches that replace a child-process launch command together with --no-zygote, causing Chromium to fork or exec an attacker-controlled command as the container's runtime user. The Docker API is unauthenticated by default, so a single request yields arbitrary command execution. This issue is fixed in version 0.9.0.
