The package js-yaml before 3.13.0 is vulnerable to Denial of service as the function storeMappingPair() in file lib/js-yaml/loader.js, doesn't limit the user supplied yaml, causing the map key to grow exponentially. giving out a huge amount of output data, leading to denial of service due to excessive memory usage.
