Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

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.
