V2Board
Monthly
Authentication bypass in V2Board 1.6.1-1.7.4 and Xboard ≤0.1.9 enables unauthenticated account takeover including admin privileges. When login_with_mail_link_enable is active, attackers POST known email addresses to the loginWithMailLink endpoint, receiving full authentication URLs in HTTP responses. Tokens extracted from these URLs are exchanged at token2Login for valid bearer tokens granting complete account access. Publicly available exploit code exists. CVSS 9.1 critical severity reflects network-accessible attack with no user interaction required.
