TP-Link Deco M5 v1 uses a weak password hashing mechanism to store user credentials. An attacker who obtains the password hash through system compromise or privileged access could perform brute-force or dictionary attacks. Successful exploitation may result in disclosure of authentication credentials, enabling unauthorized access to device management functions, depending on the privileges associated with the recovered password. The primary security impact is loss of confidentiality.
