0 CVE-2026-27859 is a medium severity vulnerability in Open-Xchange GmbH's OX Dovecot Pro mail server. It involves uncontrolled resource consumption where a mail message with an excessive number of RFC 2231 MIME parameters causes the LMTP mail delivery process to consume excessive CPU resources. This can degrade mail server performance but does not impact confidentiality or integrity. No public exploits are known. Mitigation involves using MTA capabilities to limit RFC 2231 MIME parameters or upgrading to a fixed version that limits processing. Patch status is not confirmed from the available data.
