CVE-2026-102813 · Severity: info · Published 2026-10-27

The TP-Link RE305 V3 range extender contains a flaw in its password-recovery feature that allows anyone on the local network to reset the administrator password without authentication. An attacker can exploit the lack of rate-limiting and predictable code generation to obtain or brute-force the verification code, gaining full administrative control over the device and its network functions.

## Technical details

An unauthenticated attacker on the local network can trigger password-reset verification-code generation through an inadequately protected interface. The verification-code mechanism lacks rate-limiting or lockout, and uses predictable code generation, allowing the attacker to brute-force or obtain the code to reset the administrator password and access privileged device-management functions.
