Short explanation
A DQL injection vulnerability exists in Dynatrace MCP Server because several read capabilities interpolate caller-controlled values into DQL without sufficient validation or escaping.
This vulnerability allows callers to bypass the narrower auto-approved tool contract and display limits of tools marked with readOnlyHint.
What should be done?
- Updating the software to version 2.1.1 or later
- Following vendor advisories
Chain of evidence and sources
Dynatrace MCP Server 2.1.1 öncesi sürümlerde, bazı okuma yetenekleri çağrı yapanlar tarafından kontrol edilen değerleri yeterli doğrulama olmaksızın DQL içine eklemektedir.

Show the technical text from the sources
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.
