CVE-2026-123810
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.

Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
