Summary

FreeMail before 5.3.2 contains an authorization bypass vulnerability that allows authenticated users to claim another user's existing mailbox via the POST /api/create endpoint. Knowing the victim's address, an attacker can become a co-owner and read messages and verification codes, set forwarding, and delete mail.

Risk Assessment

An attacker could take control of a victim's mailbox, gaining access to confidential correspondence and verification codes. This may lead to further account takeovers and data loss.

Recommendation

Update FreeMail to version 5.3.2 or later. Review logs for unauthorized mailbox assignments and verify co-owner permissions.
