Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

CasaOS Gateway versions before 0.4.4 are vulnerable to incorrect identification of client IP addresses, which lets unauthenticated attackers execute arbitrary commands as root. The source does not describe the exact request path involved. Upgrade to CasaOS Gateway 0.4.4, which contains the fix; if upgrading is not possible, restrict access to CasaOS from untrusted users, such as by not exposing it publicly.
