CVE-2026-85654

Host code execution via unneutralized model names

Published Sep 4, 2026 · Updated Sep 4, 2026

Code injection in AWS DynamoDB MCP Server 2.0.10 through 2.1.5 allows context-dependent attackers to execute code during CDK deployment. The CDK generator inserts table, index, or attribute names from dynamodb_data_model.json into generated application templates without neutralizing code syntax. Exploitation requires a crafted model file to reach the generator and the resulting application to be deployed, which executes the injected code on that host.
