CVE-2023-6036: 
WordPress vulnerability analysis and mitigation

The Web3 WordPress plugin before version 3.0.0 contains an authentication bypass vulnerability (CVE-2023-6036) discovered in January 2024. The vulnerability exists due to incorrect authentication checking in the login flow, specifically in the functions 'handle_auth_request' and 'hadle_login_request'. This security flaw affects the Web3 - Crypto wallet Login & NFT token gating plugin for WordPress (NVD, WPScan).

The vulnerability is classified as an authentication bypass (AUTHBYPASS) with a CVSS score of 9.8 (Critical), indicating the highest severity level. The vulnerability is tracked as CWE-863 (Incorrect Authorization) and allows attackers to bypass authentication controls. The technical implementation flaw lies in the login flow functions, where improper authentication checking can be exploited (WPScan).

The vulnerability allows unauthenticated attackers to log in as any existing user on the site, including administrators, provided they have access to the username. This level of access could potentially lead to complete site compromise, as attackers could gain administrative privileges (NVD).

The vulnerability has been patched in version 3.0.0 of the Web3 WordPress plugin. Users are strongly advised to update to this version or later to protect against potential exploitation (WPScan).
