    CVE-2026-40608 (GCVE-0-2026-40608)

    Vulnerability from nvd – Published: 2026-04-21 17:56 – Updated: 2026-04-21 18:36

    Title
    Next AI Draw.io: Unbounded HTTP Body — Denial of Service
    Summary
    Next AI Draw.io is a next.js web application that integrates AI capabilities with draw.io diagrams. Prior to 0.4.15, the embedded HTTP sidecar contains three POST handlers (/api/state, /api/restore, and /api/history-svg) that process incoming requests by accumulating the entire request body into a JavaScript string without any size limitations. Node.js buffers the entire payload in the V8 heap. Sending a sufficiently large body (e.g., 500 MiB or more) will exhaust the process heap memory, leading to an Out-of-Memory (OOM) error that crashes the MCP server. This vulnerability is fixed in 0.4.15.
