Bug# Summary CVE-ID CVSS Score Zimbra Rating Fix Release or Patch Version
109174 Non-Persistent XSS – admin console CVE-2019-12427 4.3 Minor 8.8.15 P1
109141 Non-Persistent XSS – web client CVE-2019-15313 4.3 Minor 8.8.15 P1

Zimbra 8.8.12 “Isaac Newton” Patch 5

Patch 5 is here for the Zimbra 8.8.12 “Isaac Newton” GA release, and it includes fixes as listed in the release notes.

Fixed Issues

CSS display attribute is now configurable in OWASP allowing users to have better control over HTML rendering elements.
Introduction of OWASP sanitization caused HTML action buttons shown in emails to open the links inside the email preview pane. They now open in a new tab or window.
The zimbraLastLogonTimeStampFrequency setting now limits the frequency of updates to the ‘’lastLoginTimeStamp’’ in ephemeral data storage, reducing the load for syncing those changes in multi-node systems.

Thank you,
Your Zimbra Team
