Affected: unclecode crawl4ai

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.

Affected: PyPI: crawl4ai

### Summary

The Docker API server accepted a 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 (`--utility-cmd-prefix`, `--renderer-cmd-prefix`, `--gpu-launcher`, `--browser-subprocess-path`) together with `--no-zygote`, causing Chromium to fork/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.

The earlier `extra_args` SSRF patch (0.8.9) used a denylist scoped to proxy/DNS flags; a denylist of launch switches is inherently incomplete, and these command-execution switches were not covered.

### Affected paths

`/crawl`, `/crawl/stream`, `/crawl/job` accepting a request `browser_config.extra_args`.

### Impact

Unauthenticated remote code execution as the container runtime user; full read/write of application data, mounted secrets, environment, and tokens, and out-of-band exfiltration independent of the HTTP response.

### Fix

0.9.0 establishes a trust boundary for request-supplied configuration: `extra_args` (along with other power fields such as `proxy`, `user_data_dir`, `cdp_url`, `init_scripts`) is a forbidden field for untrusted request bodies. Any request that sets `extra_args` is rejected with HTTP 400 rather than scrubbed against an always-incomplete denylist. In-process SDK callers (trusted) are unaffected.
