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

Description

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.

Affected Packages / Versions

• Package: openclaw (npm)
• Affected: <=2026.2.14
• Patched (planned next release): >=2026.2.15
• Latest published npm version at triage time (2026-02-16): 2026.2.14

Remediation

Array ordering is now preserved during hash normalization; only object key ordering remains normalized for deterministic hashing.

Release Process Note

patched_versions is pre-set to the planned next release (2026.2.15) so after npm publish, the advisory can be published directly without reopening version metadata edits.
