0 A vulnerability in the MCP TypeScript SDK and server allows a single HTTP request within the default 4 MiB size limit to exhaust server memory during validation by sending excessive array elements or object keys. This causes the server process to abort with a 'JavaScript heap out of memory' error. No authentication is required unless the server enforces it before the SDK processes requests. The issue affects versions 1.3.0 through 1.31.0 of @modelcontextprotocol/sdk and 2.0.0 through 2.2.0 of @modelcontextprotocol/server. Fixed versions are 1.32.0+ for the SDK and 2.3.0+ for the server, which introduce a new option to limit input elements and recommend lowering request size limits.
