CVE-2026-123812
Published:November 09, 2026
Updated:November 10, 2026
Dynatrace MCP Server is an MCP server for Dynatrace Observability. Prior to 1.8.7, the create_dynatrace_notebook registration in src/index.ts performs a persistent document-write action without calling requestHumanApproval, although the project's other write tools use that gate to obtain operator consent. A caller can create tenant-visible notebooks containing attacker-controlled Markdown or DQL content, and tenant users may later execute embedded DQL when opening the notebook. The tool also lacks a destructiveHint annotation that would signal its side effects to MCP clients. This issue is fixed in version 1.8.7.
