Changelog published on 26 October 2026​

Vulnerability fixes​

  • BM-24457: [Critical] Sanitised attribute values are now correctly escaped.
  • BM-24458: [Critical] The access denied page no longer displays the login in plain text.
  • BM-24507: [Minor] Upgraded the Java dependency async-http-client to version 3.0.14 (CVE-2026-107230).

BlueMind Applications​

BlueMind Webmail (Mail App)​

  • BM-24348: Fixes: Encrypted drafts become corrupted when exiting the editor whilst saving. An unreadable section no longer forms part of the content of an encrypted or signed email. A signed email whose content cannot be found now displays an unknown signature status.
  • BM-24356: Fixes: Search terms are not always highlighted in the body of emails.
  • BM-24383: Fixes: Switching to another application whilst sending an email causes the email to become stuck in the outbox.
  • BM-24409: Fixes: In certain cases, an email in the format text/plain containing a specific HTML tag is misinterpreted and displayed incorrectly.
  • BM-24503: Fixes: The file repository removes its drag-and-drop handles when closed.

Contacts​

  • BM-23955: Fix: An invalid image used as a contact photo displays an error message instead of an empty cropped area.
  • BM-24323: Fixes: The browser’s "Return" button no longer takes you back to the previous application: you remain in Contacts.
  • BM-24410: Special characters are displayed verbatim in the legacy contact autocomplete, search highlighting, contact suggestions and the contact card note.

MAPI / Outlook​

  • BM-24505: Fixes: After replying to a meeting from Outlook, the meeting appears twice in Outlook or disappears from the calendar. Replying to an invitation from Outlook now continues to work when the mailbox’s MAPI status is reloaded (logging out of another Outlook instance, changing delegation, or resetting sessions).

Mobile Devices (EAS)​

  • BM-24438: Fixes: Replying to a plain-text email (content-type "format=flowed") from a mobile phone merges all rows.

Preferences​

  • BM-24097: Fixes: Preferences no longer offer the option to share address books, calendars and to-do lists from a shared mailbox.

DAV (CalDAV / CardDAV)​

  • Feature: CardDAV now displays all address books synchronised by the user (My Contacts, Collected Contacts, Shared Address Books, Domain Directory). Offline synchronisation of the domain directory is disabled by default, and Apple clients still only see ‘My Contacts’.

Administration / Architecture​

Authentication​

  • Fixes: A ‘sudo’ login from the administration console writes the session token to the logs. Only the login is now subject to journaling.

Administration console​

  • BM-24350: Fixes: When the highest sharing right is granted to a mailbox, the associated delegation can no longer be managed.

AD / LDAP​

  • BM-24183: Fix: Incremental AD and LDAP imports now apply changes to the split domain made via sub-groups. The import log shows the group used, and the LDAP import no longer hangs when two groups are members of one another.

Directory​

  • Fix: Only an organizational unit manager can modify the administrators of a unit. A delegate can only grant or revoke the roles that they hold within the unit.
  • Fix: Only a domain administrator can remove a user from the list of administrators for all organizational units within the domain.
  • Fix: An organizational unit delegate can no longer move an external user from the domain root or another unit into their own unit.
  • Fix: An organizational unit delegate can no longer move a domain address book or calendar outside their unit (to the domain root or another unit).
  • Fix: Moving an address book or domain calendar to another unit is now processed immediately: delegates from the old unit immediately lose their access rights to it.
  • Fix: Only a user with the "check&repair" role can initiate the repair of a directory entry within the domain of that entry. Domain administrators and the relevant unit can still initiate the repair.

API​

  • Fix: The Kerberos key (keytab) is no longer returned in plain text by the domains API: it is displayed in the format ****. Saving a domain via the console retains the existing key if the value is hidden or empty.

Clone​

  • Fixes: Deleting and then recreating a user or shared mailbox with the same login name causes the cloning process to fail.

Containers​

  • Fix: The list of a user’s containers now only displays those to which the user has access (their own, those shared with them, or those belonging to a user or shared mailbox that they manage).

Core​

  • BM-24010: Fixes: The cache is not invalidated when a user is deactivated; consequently, a deactivated user can still send emails via SMTP.

DataProtect​

  • Fix: A domain administrator can now only restore data from their own domain. Administrators of the relevant domain and holders of the manageDataProtect role can still do so.

Permissions and Roles​

  • Fix: A domain administrator can no longer make changes to mailboxes, groups or settings in another domain (quota, filter, index consolidation, reading settings, etc.).
  • Fix: Administrators of users, groups, shared mailboxes, resources, address books and domain calendars can now only perform actions (share, rename, configure, publish, synchronise, reset) on containers of that specific entry type. The domain S/MIME certificate manager no longer has any rights over containers. Domain administrators and unit delegates retain their rights.

Indexing​

  • Fix: A re-indexing request (for calendars, address books, to-do lists, notes) made without the necessary permissions is rejected immediately, without launching a task that would subsequently fail. The required permissions remain unchanged.

Keycloak​

  • Fix: Modifying a domain’s authentication settings no longer writes the Kerberos key or the OpenID client secret to the logs. Only the name of the modified property is logged.

Mail (mailbox)​

  • Fix: The ‘Read domain filters’ role no longer allows users to add, edit or delete domain filter rules. These actions require the ‘Manage mail filters’ role.
  • Fix: Only a system administrator can add or remove an index from the mail index ring. A domain administrator now receives a permission error.

Monitoring​

  • BM-24328: Fixes: An inactive BlueMind server constantly shows 100% CPU utilisation in iowait.
  • Fix: Reading installation alerts now requires the bmMonitoring role. The global administrator retains access.

Sessions (KeyDB)​

  • Fix: The web server no longer blocks its event loop whilst searching for a session, even when KeyDB responds slowly.

System​

  • Fix: Only users with the systemManagement or bmMonitoring role can view hot upgrades (ongoing, scheduled jobs, and completed tasks, and their progress). Launching them requires the systemManagement role. The notification regarding failed mandatory hot upgrades continues to be displayed to administrators.
  • Fix: An internal call to the core can no longer modify or delete a global parameter without the systemManagement role, even when using a domain administrator’s context.
