CVE-2026-107824: x64dbg-MCP Server
The National Vulnerability Database (NVD) record says that before version 1.1 x64dbg-MCP Server, a Model Context Protocol (MCP) plugin for the x64dbg debugger, exposed its debugger tools over HTTP without authentication on 0.0.0.0 by default, so any network client that can reach the port can execute arbitrary x64dbg commands, read and write debuggee memory, and write files to arbitrary paths; fixed in 1.1.

What a signal is. A signal records what a primary record says; it assigns no fault. It is lighter than a case: one dated item from one record, tagged with the world, sector and controls it touches. It becomes a case when it meets the bar for one.
