CVE-2025-23222

Summary

CVE-2025-23222 is a vulnerability affecting Deepin dde-api-proxy through version 1.0.19. The issue allows unprivileged users to access D-Bus services as root due to the way dde-api-proxy forwards messages. Dde-api-proxy runs as root and relays messages from local users to legacy D-Bus methods in actual D-Bus services, giving the false impression that root is making requests. As a result, several methods not intended for non-root users become accessible, potentially resulting in privilege escalation when Polkit is involved, allowing callers to be treated as administrators.
