Uncaught Exception in org.webjars.npm:undici

Summary

Impact: The undici WebSocket client is vulnerable to a denial-of-service attack due to improper validation of theserver_max_window_bitsparameter in the permessage-deflate extension. When a WebSocket client connects to a server, it automatically advertises support for permessage-deflate compression. A malicious server can respond with an out-of-rangeserver_max_window_bitsvalue (outside zlib's valid range of 8-15). When the server subsequently sends a compressed frame, the client attempts to create a zlib InflateRaw instance with the invalid windowBits value, causing a synchronous RangeError exception that is not caught, resulting in immediate process termination. This issue affects undici versions prior to 6.24.0 and 7.x versions prior to 7.24.0. The vulnerability exists because: * TheisValidClientWindowBits()function only validates that the value contains ASCII digits, not that it falls within the valid range 8-15 * ThecreateInflateRaw()call is not wrapped in a try-catch block * The resulting exception propagates up through the call stack and crashes the Node.js process
