CVE-2026-57572 Details
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.
A remote code execution vulnerability has been identified in Crawl4AI versions prior to 0.9.0. The issue arises because the Docker API server accepted request-supplied 'browser_config.extra_args', which were passed directly into Chromium's launch arguments. This allowed an attacker to inject commands that could be executed as the container's runtime user. The vulnerability is particularly concerning because the Docker API is unauthenticated by default, enabling arbitrary command execution with a single request.
Users are advised to upgrade to Crawl4AI version 0.9.0 or later, which addresses the vulnerability by rejecting untrusted 'extra_args' in API requests. Enabling authentication and restricting API access can also help mitigate the issue.
