ThingsBoard could let attackers decode encrypted data
published 5 days ago
Summary
The ThingsBoard platform uses a default setting that may allow a skilled attacker to read information that should be hidden. This could expose sensitive data or let someone modify it without permission. Upgrade to the latest version of ThingsBoard or adjust the security configuration as recommended by the vendor to close the gap.
What to do
- Update cleanstart thingsboard to version 4.3.1-r0.
