This report evaluates 14 sandbox solutions for AI coding agents across four isolation tiers (containers, user-space kernels, microVMs, kernel-enforced capabilities), documents multiple real-world isolation failures (credential exposures, allowlist/environment poisoning CVE-2026-22708, prompt-injection/code execution), and concludes that sandboxing limits blast radius but does not solve the underlying trust problem; it recommends threat-model-driven sandbox selection, defense-in-depth, dual-isolation, and violation detection.
