CVE-2025-27217Network attack vector

Authenticated access to out-of-scope network resources

Published Aug 21, 2025 · Updated Aug 21, 2025

Server-side request forgery in Ubiquiti UISP Application 2.4.211 and earlier allows remote authenticated users to access out-of-scope resources. Ubiquiti has not disclosed the affected endpoint or the request-handling operation that fails to constrain attacker-controlled destinations. Access requires certain account permissions, and the vendor bounds the reported consequence to confidentiality exposure through server-originated requests.
