CVE-2026-18330

Summary

A hard-coded cryptographic key vulnerability exists in the web module of TP-Link Archer AX55 v4. A LAN attacker who captures an HTTP login session may use the known shared RSA private key to decrypt the administrator password; the weakened AES session key further reduces the effort required to compromise session confidentiality.

Successful exploitation may disclose the administrator password captured from an HTTP login session and compromise session confidentiality.
