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."}],"source":{"advisory":"GHSA-pc2w-4mq8-32qw","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/security/advisories/GHSA-pc2w-4mq8-32qw","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-11-10T16:14:25.352854Z","id":"CVE-2026-123812","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-11-10T16:14:46.389Z"}}]}}
