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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":4.3,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1794257990956,"publishedAt":1794257990956,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/dynatrace-oss/dynatrace-mcp/security/advisories/GHSA-pqh8-p93p-2rx7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/dynatrace-oss/dynatrace-mcp/commit/15d3546c0618ffbaeaeca477337e08e92f2151bc"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/dynatrace-oss/dynatrace-mcp/releases/tag/v2.1.1"}],"remediation":[],"revision":"436ce07493be1776eef52fc913b6538788087e0184123b1e4eeaf76407210321","sources":[{"modifiedAt":1794257990956,"name":"CNA: GitHub_M","retrievedAt":1794258573668,"url":"https://www.cve.org/CVERecord?id=CVE-2026-123810"}],"ssvc":null,"status":"published","title":"Dynatrace MCP Server: DQL injection via parameters not documented as DQL","updatedAt":1794258573668}
