CVE-2026-79316Network attack vector

Management service exposure via unchecked binding template

Published Sep 21, 2026 · Updated Sep 21, 2026

Improper access control in x-ui 0.3.2 allows remote authenticated users to expose the Xray management gRPC service to other hosts. The settings save path checks only JSON syntax, then the restart path writes the user-controlled template verbatim into the runtime configuration without constraining the management address or port. A valid panel login and a restart are required; when perimeter rules permit the new listener, other hosts can reach management functions for runtime changes, logs, and statistics.
