Sync-in/server v2.3.0

on GitHub

⭐ Highlights

• Integrated Markdown editor: visual/source Markdown editing with tables, task lists, images, code blocks, file locking and unsaved-change protection
• Unified editor search: shared search UI for text and Markdown editors, with result count and previous/next navigation
• Configurable document creation: administrators can show or hide OpenDocument and Microsoft Office templates
• Optional trash retention: automatic cleanup can now be configured separately for user spaces and collaborative spaces
• Improved content indexing: more memory-efficient full-text indexing, batched metadata processing and safer cleanup
• OIDC/LDAP synchronization extended: OIDC avatar synchronization and storage quota synchronization through LDAP attributes or OIDC claims
• User visibility controls: users without a group can now be hidden from global visibility with showUngroupedUsers: false
• Text and Markdown editing improvements: better text file detection and increased edit size limit from 10 MB to 25 MB

🐞 Bug Fixes

• Guest link temporary paths: temporary paths for accounts associated with guest links are now created correctly
• File storage consistency: stronger uniqueness checks prevent rare duplicate file storage cases (@zjean)
• More reliable file unlocking: editable file locks are now released more reliably when editors or the browser are closed
• MIME type updates: MIME types are now recalculated after file rename, move or replacement
• Disabled space trash handling: trash for disabled spaces is now shown as disabled and can no longer be browsed
• Improved file selection: range selection works more reliably with filtering enabled
• Safer renaming: renaming now selects only the file name, without the extension
• Web interface polish: sidebar submenu visibility, table row height, dialog spacing and viewer tooltips were refined

⚠️ Security

• Trash immutability for spaces
  Files in the trash are now treated as read-only items. Modifying files in the trash and creating new files there are now blocked.

• More reliable uploads
  Failed uploads are no longer kept in the destination space. File replacements now use temporary files before replacing the destination.

• Better guest link isolation
  Accounts created from guest links now have restricted visibility over users and groups, limited to their managers and personal groups.

• Fixed a security vulnerability: CVE-2026-47684
  SSRF protection for URL downloads has been strengthened, notably against IPv4-mapped IPv6 bypasses, DNS rebinding, unsafe redirects, proxy bypasses and oversized data streams.
