CVE-2025-55630Network attack vector

Account enumeration via distinguishable login errors

Published Aug 22, 2025 · Updated Aug 22, 2025

Account enumeration in Reolink Smart 2K+ Plug-in Wi-Fi Video Doorbell firmware 3.0.0.4662_2503122283 allows remote attackers to identify users. The login function returns distinguishable error messages for invalid usernames and incorrect passwords, exposing whether a submitted account exists. No authentication or user interaction is required; repeated network login attempts reveal valid account names but do not themselves grant account access.
