CVE-2026-71264Network attack vector

Unauthenticated configuration disclosure and cross-client settings unlock

Published Aug 5, 2026 · Updated Aug 5, 2026

Missing authorization in Aircoookie WLED allows remote attackers to read configuration and, after any PIN unlock, write configuration. The GET /json/cfg handler calls serveJson without a settings-PIN check, while one global correctPIN boolean shares a single client unlock with every client. Network access is sufficient for disclosure; after the four-digit PIN is entered once, the shared unlock permits WiFi changes, factory reset, and OTA firmware updates until reboot.
