CVE-2026-27007

OpenClaw's sandbox config hash sorted primitive arrays and suppressed needed container recreation

4.8 MediumFix available

OpenClaw is a personal AI assistant. Prior to version 2026.2.15, normalizeForHash in src/agents/sandbox/config-hash.ts recursively sorted arrays that contained only primitive values. This made order-sensitive sandbox configuration arrays hash to the same value even when order changed. In OpenClaw sandbox flows, this hash is used to decide whether existing sandbox containers should be recreated. As a result, order-only config changes (for example Docker dns and binds array order) could be treated as unchanged and stale containers could be reused. This is a configuration integrity issue affecting sandbox recreation behavior. Starting in version 2026.2.15, array ordering is preserved during hash normalization; only object key ordering remains normalized for deterministic hashing.
