CasaOS contains weak JWT secrets

Impact

Unauthenticated attackers can craft arbitrary JWTs and access features that usually require authentication and execute arbitrary commands as root on CasaOS instances.

Patches

The problem was addressed by improving the validation of JWTs in 705bf1f. This patch is part of CasaOS 0.4.4.

Workarounds

Users should upgrade to CasaOS 0.4.4. If they can't, they should temporarily restrict access to CasaOS to untrusted users, for instance by not exposing it publicly.
