Vulnerability description

DayBreach CVE AI Research

CVE-2026-33606 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

Mail content stored by a user can be crafted so that it is interpreted as dsync protocol commands when an administrator later runs dsync with the stream protocol, for example during a migration. Injected commands can modify mailbox state on the destination during migration or replication, including internal mailbox attributes that a user should not be able to set directly. It can also cause dsync errors. Avoid running dsync with the stream protocol on mailboxes with untrusted content. Update to non-vulnerable version. No publicly available exploits are known.
