Description

OpenClaw before 2026.5.22 contains a locality validation vulnerability in Control UI pairing that allows attackers with network access to spoof locality information and obtain durable admin-capable device tokens. Attackers can exploit insufficient locality-derived trust validation to convert temporary shared access into persistent administrative credentials that survive token rotation.
