CVE-2026-19683
Unencrypted Credential Transmission in Omada Gateway Dynamic DNS Authentication in Omada Gateways
No known exploitation. EPSS puts it in the 14th percentile. A vendor fix is available.
What to do
The vendor has published a fix. Version details are below where the sources state them.
What it is
From the CVE record
A vulnerability exists in the Dynamic DNS (DDNS) functionality of TP-Link Omada Gateways. During communication with a third-party DDNS service, authentication credentials are transmitted over an unencrypted channel. An attacker who can observe or manipulate traffic between an affected device and the DDNS service may obtain sensitive authentication information or interfere with DDNS update operations. Exploitation requires DDNS to be configured, communication with an external DDNS service, and attacker visibility or control of the relevant network path. Successful exploitation may result in disclosure of DDNS account credentials, unauthorized access to DDNS management functionality, or modification of DNS records associated with the affected deployment.
