TrueConf Server: Security Updates for June 2026
We have released an important security update for June 2026. We recommend immediately upgrading to the latest versions of TrueConf Server — 5.3.9, 5.4.9 and 5.5.5.
Declining to install the updates will reduce the protection of your video collaboration system against potential hacker attacks via the public Internet.
Important! The updates are free for both corporate and free versions of TrueConf Server. Re-registration is not required when updating from:
- from 5.5.X to 5.5.5
- from 5.4.X to 5.4.9
- from 5.3.X to 5.3.9
For versions 5.2 and below — contact the manager or technical support.
We recommend checking the guide and creating a backup copy before installing the update. If you encounter issues starting TrueConf Server after the update, use your key to re-register the server.
For any questions, please contact TrueConf technical support.
