GHSA-PM4M-PH32-GHV5 js-yaml: Exponential parsing time in flow collections leads to denial of service

Summary Parsing a small YAML document can take exponential time. An application that calls load or loadAll on untrusted input can be hung by a payload under 200 bytes. Details When an entry in a flow sequence turns out to be a key: value pair, the parser rewinds and parses that entry a second tim...
