An information disclosure vulnerability has been identified in Omada Controller. An API endpoint intended for Controller initialization remains accessible after completion and may disclose account-related information to unauthenticated remote users. Successful exploitation may allow an attacker to remote query the affected endpoint that may facilitate user enumeration and subsequent attacks targeting administrative accounts.
