CVE-2026-47427: CWE-476: NULL Pointer Dereference in github github-mcp-serverCVE-2026-47427 0 GitHub MCP Server is GitHub's official MCP Server. Prior to 1.1.0, the CompletionsHandler function in pkg/github/server.go accesses params.Ref without first checking whether it is nil, so a completion/complete request with a missing or empty ref field triggers a nil pointer dereference and a Go runtime panic; because the crash occurs before any authentication or token validation, any unauthenticated client able to send JSON-RPC messages can crash the server, resulting in a complete denial of service. This issue is fixed in version 1.1.0. Join the discussion | CVE Database V5 | 07/28/2026, 15:32:27 UTC Added: 07/28/2026, 16:22:55 UTC |
