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.\n\nThe 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.\n\n### Affected paths\n\n`/crawl`, `/crawl/stream`, `/crawl/job` accepting a request `browser_config.extra_args`.\n\n### Impact\n\nUnauthenticated 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.\n\n### Fix\n\n0.9.0 establishes a trust boundary for request-supplied configuration: `extra_args` (along with other power f","public_affected_ranges":["<= 0.8.9"]}],"null_published_at":"2026-11-07T07:07:39.863Z","source_updated_at":"2026-06-18T17:25:36.000Z","source_disclosed_at":"2026-06-18T17:25:34.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-06T07:20:10.578Z"}],"next_cursor":null,"snapshot_revision":"42594"}
