CVE-2025-30237

Unauthenticated privileged operations via missing endpoint authorization

Published Aug 10, 2026 · Updated Aug 10, 2026

Authentication bypass in TP-Link Aginet device firmware allows remote attackers to invoke privileged operations without credentials. The web interface omits consistent authentication checks on sensitive endpoints, but TP-Link has not identified the affected handlers or requests. Exploitation requires adjacent network access and grants control of device configuration and operations.
