CVE-2026-56264: Kidocode CRAWL4AI

Medium severity, CVSS 6.1. EPSS: 0.5% chance of exploitation in the next 30 days.

Crawl4AI before 0.8.7 contains an arbitrary JavaScript execution vulnerability in the Docker API server's /execute_js endpoint, which accepts and executes arbitrary user-supplied JavaScript in the server's browser context with --disable-web-security enabled. An attacker can execute arbitrary JavaScript and, combined with the browser's relaxed security settings, perform server-side request forgery against internal services.
