CVE-2026-10123: TRENDnet TEW-432BRP: Remote attack possible through router settings
CVE-2026-10123
Summary
A security risk was found in a very old version of the TRENDnet TEW-432BRP router software. This means that a remote attacker could potentially access and manipulate the router's settings. Since this router model is no longer supported by the manufacturer, it's unlikely to be fixed, but it's still a good idea to consider replacing it for security reasons.

As the item has been EOL for such a long time, we are not able to replicate or fix any vulnerabilities." This vulnerability only affects products that are no longer supported by the maintainer.
