CVE-2023-37266
CasaOS contains weak JWT secrets
Impact
### 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. ### References - 705bf1f - https://www.sonarsource.com/blog/security-vulnerabilities-in-casaos/
