description

x64dbg-mcp-server versions before 1.1 can expose debugger operations without authentication when using the default network listener. A remote client that can reach the service may control debugging actions, interact with processes and their memory, and cause files to be written. Exposure requires network access to the running service.

mitigation

Upgrade x64dbg-mcp-server to version 1.1 or later. Until upgraded, restrict access to the service with network controls and avoid exposing its listener beyond trusted hosts.
