Axios: ReDoS in fromDataURI data: URL parser freezes the Node event loop (DoS)

Summary Axios for Node.js parses data: URLs in lib/helpers/fromDataURI.js. The current RFC-2397 parser uses a regular expression whose media type groups allow / inside both sides of the type/subtype match. A malformed data: URL containing many slashes and no comma forces the JavaScript regex engi...
