CVE-2026-123811

7.5 HIGH 0.2% exploit odds Fix listed Auth & access Server

What it is

Dynatrace MCP Server is an MCP server for Dynatrace Observability. Prior to 2.0.0, a server started with the --http option accepts JSON-RPC tools/call requests without authentication, session validation, or Host and Origin protections before dispatching them under the server's configured Dynatrace credentials. A network-reachable caller can invoke execute_dql to read logs, security events, user sessions, and other Grail data, or invoke create_dynatrace_notebook to create tenant-visible notebooks. The send_event path is not affected because its requestHumanApproval gate blocks this attack path, and reset_grail_budget only demonstrates dispatch without accessing Dynatrace data. This issue is fixed in version 2.0.0.
