TP-Link disclosed two vulnerabilities in the Archer AX55 v4 — a stack-based buffer overflow in the EasyMesh daemon that may enable remote code execution (CVSSv4 7.7) and a hardcoded RSA-1024 private key in the web login module that can expose admin credentials (CVSSv4 6.1). Both are fixed in firmware 1.2.1 Build 20260527; users should update immediately, change admin credentials, prefer HTTPS, and disable Mesh mode if it is not required.
