CVE-2026-53817

### Summary In affected LAN/shared-token Control UI deployments, a caller could spoof locality information used during Control UI pairing and obtain a durable admin-capable device token. This issue is limited to deployments where the caller already has the network/authentication foothold needed to reach the Control UI pairing path. It is not an unauthenticated internet exposure issue. ### Affected configurations This affects configurations such as LAN-bound gateways or shared-token Control UI access where locality signals were accepted as sufficient for pairing decisions. ### Impact A temporary or shared Control UI access path could be turned into a persistent admin device token. That token could remain useful after the shared gateway token was rotated, unless the paired device was removed. The issue is a pairing/locality validation problem: locality-derived trust was stronger than it should have been. ### Patched Versions The first stable patched version is `2026.5.22`. ### Mitigations Upgrade to `[email protected]` or later. For older deployments, remove unexpected paired devices and avoid exposing Control UI pairing paths on networks with untrusted clients.
