CVE-2026-102814

Improper Authentication in TP-Link TDDP v2 Allows Root Command Execution in TP-Link RE305

Published Oct 27, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
An
authentication weakness exists in the TP-Link TDDP v2 service of TP-Link RE305
V3. TDDP v2 uses a fixed and derivable cryptographic key, which may allow an
unauthenticated attacker on the same local network to forge protocol packets
and access privileged TDDP operations, including functionality that can lead to
operating-system command execution when the TDDP service is running and
accessible.









Successful
exploitation may allow an unauthenticated attacker on the same local area
network to execute arbitrary system commands with root privileges.
