CVE-2026-102813 (GCVE-0-2026-102813)

Vulnerability from cvelistv5 – Published: 2026-10-27 17:40 – Updated: 2026-10-27 17:40

Title

Administrator Password Reset Through the Verification-Code Interface in TP-Link RE305

Summary

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. Successful exploitation may allow an unauthenticated attacker on the local network to reset the administrator password and subsequently access privileged device-management functions.
