This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.","Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable
