{"id":"CVE-2026-123810","published":"2026-11-09T22:18:37.133","lastModified":"2026-11-10T17:17:24.123","description":"Dynatrace MCP Server is an MCP server for Dynatrace Observability. Prior to 2.1.1, several read capabilities interpolate caller-controlled values into DQL without sufficient validation or escaping. The src/capabilities/find-monitored-entity-by-name.ts capability embeds entityNames in string searches, src/capabilities/list-problems.ts, src/capabilities/list-vulnerabilities.ts, and src/capabilities/list-exceptions.ts embed timeframe values, and src/capabilities/get-events-for-cluster.ts embeds timeframe, clusterId, and kubernetesEntityId. Crafted values can close string literals, append pipeline stages, or comment out the remaining intended query, allowing callers to bypass field selection, time-window, and result-display limits in tools marked readOnlyHint. The issue does not grant data access beyond the configured token's existing execute_dql capability, but it breaks the narrower auto-approved tool contract. This issue is fixed in version 2.1.1.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","cwes":["CWE-89"],"vendors":[],"products":[],"references":[{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/commit/15d3546c0618ffbaeaeca477337e08e92f2151bc","tags":[]},{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/releases/tag/v2.1.1","tags":[]},{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/security/advisories/GHSA-pqh8-p93p-2rx7","tags":[]},{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/security/advisories/GHSA-pqh8-p93p-2rx7","tags":[]}],"exploitRefs":[{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/commit/15d3546c0618ffbaeaeca477337e08e92f2151bc","tags":[]},{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/releases/tag/v2.1.1","tags":[]},{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/security/advisories/GHSA-pqh8-p93p-2rx7","tags":[]},{"url":"https://github.com/dynatrace-oss/dynatrace-mcp/security/advisories/GHSA-pqh8-p93p-2rx7","tags":[]}],"hasPoc":true,"ai":null}
