Vulnerability details
The vulnerability allows a remote attacker to reset two-factor authentication secrets for arbitrary accounts.
The vulnerability exists due to missing authentication for a critical function in the ga_generate_qr handler in app/sources/main.queries.php when handling crafted unauthenticated requests with demand_origin set to users_management_list. A remote attacker can send a specially crafted request to reset two-factor authentication secrets for arbitrary accounts.
The issue can affect existing users including administrators, and the operation overwrites the stored ga and ga_temporary_code values without requiring the target password.
