Unknown · Next-Ai-Draw-Io · CVE-2026-40608
**Name of the Vulnerable Software and Affected Versions**
Next AI Draw.io versions prior to 0.4.15
**Description**
The embedded HTTP sidecar contains three POST handlers, ''/api/state'', ''/api/restore'', and ''/api/history-svg'', which process incoming requests by accumulating the entire request body into a JavaScript string without size limitations. Because Node.js buffers the entire payload in the V8 heap, sending a sufficiently large body can exhaust the process heap memory, resulting in an Out-of-Memory (OOM) error that crashes the MCP server.
**Recommendations**
Update to version 0.4.15.
