Components: Hosted 3CX Window: 2026-06-05T21:00:00+00:00 → 2026-06-05T22:00:00+00:00 3CX has today released an urgent security hotfix addressing a vulnerability in a third-party component used by the 3CX platform. As part of our ongoing commitment to keeping your services secure and up to date, our technical team is now rolling out this update across all affected systems. **What this means for you** You don't need to take any action, as we are applying the update on your behalf. During the maintenance window you may experience a brief interruption to calls as each system is updated and restarted. We are scheduling the work to minimise disruption and will complete it as quickly as possible. **What we're doing** Our engineering team is deploying the latest 3CX security release across our hosted estate in a controlled, phased manner to ensure stability throughout. We are monitoring each system closely as the update is applied. **Timescales** We expect the rollout to be completed shortly. If you have any questions or notice any issues with your service, please contact our support team in the usual way. Thank you for your patience as we carry out this important work.
