Account takeover via unbound password reset token
Published Sep 30, 2025 · Updated Sep 30, 2025
Authentication bypass in TitanSystems Zender 3.9.7 allows remote attackers to take over user accounts through password reset. The forgot-password flow issues a temporary password for one account but accepts that credential with a different email address during login. Exploitation requires control of one account's reset credential and grants the victim account's access, including administrative privileges.
