Dovecot 2.3.11.3 Access Bypass
Posted Jan 7, 2021
Authored by Aki Tuomi

Dovecot versions 2.2.26 through 2.3.11.3 suffer from a bypass issue. When imap hibernation is active, an attacker can cause Dovecot to discover file system directory structure and access other users' emails using a specially crafted command. The attacker must have valid credentials to access the mail server.
