Reflected XSS in Garmin WDU v1 1.4.6 and v2 5.0 allows attackers on the local network to gain administrator-level device access. The locally served website renders attacker-controlled URL input without neutralization, causing JavaScript to execute in the WDU page context. The victim must open the crafted URL and click an element; Garmin has not identified the affected handler or parameter.
