CVE-2026-57572
CWE-88Published: July 6, 2026· Updated: Jul 8, 2026
Official 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.
Risk Analysis
This critical vulnerability in Crawl4AI allows unauthenticated attackers to execute arbitrary commands on the Docker container. By injecting Chromium switches, an attacker can replace a child-process launch command, leading to full system compromise. The CVSS score of 10.0 highlights the extreme severity of this flaw.
No public exploit is currently known for this vulnerability. However, its remote exploitability and lack of authentication make it a high-risk target.
Upgrade Crawl4AI to version 0.9.0 or later to fix the issue where browser_config.extra_args are improperly handled.
Technical Analysis
CVE-2026-57572 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
