Summary

MacCMS v10 before 2026.1000.4054 contains an authentication bypass vulnerability that allows unauthenticated attackers to reset any member's password because check_msg() never compares msg_to. Attackers can request a recovery code to their own mailbox via user/findpass_msg, then submit it to user/findpass_reset with the victim's email or phone to take over the account.
