Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the /_server-islands/[name] route handler, which buffers and parses the entire request body as JSON without enforcing a size limit. An attacker can cause the server process to exhaust available memory and crash by sending a single unauthenticated request with a crafted payload containing many small JSON objects, resulting in significant memory amplification.
