{"id":"CVE-2026-102813","state":"PUBLISHED","title":"Administrator Password Reset Through the Verification-Code Interface in TP-Link RE305","description":"An authentication flaw exists in the password-recovery functionality of TP-Link RE305 V3. The verification-code interface allows an unauthenticated attacker on the same local network to trigger generation of an administrator password-reset verification code. Because the interface lacks an effective attempt counter or lockout mechanism and uses a predictable verification-code generation process, an attacker may obtain or brute-force the code and reset the administrator password. \n\n\n\n\n\nSuccessful exploitation may allow an unauthenticated attacker on the local network to reset the administrator password and subsequently access privileged device-management functions.","publishedAt":"2026-10-27T17:40:31.857Z","updatedAt":"2026-10-27T17:40:31.857Z","severity":{"score":6.1,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:A/AC:H/AT:N/PR:N/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N","source":"TPLink"},"assigner":"TPLink","products":["TP-Link Systems Inc.
