CVE-2026-79316: Improper access control vulnerability

An improper access control vulnerability exists in x-ui 0.3.2. Any authenticated panel user can modify the xray configuration template through the settings interface and trigger a panel restart, causing the xray management gRPC service, which is bound to loopback by default, to be regenerated and bound to non-loopback addresses. This expands the reachable surface of the management interface beyond its intended local-only boundary.
