CVE-2025-70833Public exploitNetwork attack vector

Unauthenticated account takeover via trusted POST identity

Published Feb 20, 2026 · Updated Feb 20, 2026

Authentication bypass in Smanga 3.2.7 allows remote attackers to reset any user's password through a crafted account-update request. The check_user_power() function in /app/php/public/check-power.php authorizes requests using the client-supplied POST userId rather than a server-side session identity. No login session is required; setting userId and targetUserId to an administrator account lets the attacker replace its password and take over that account.
