GHSA-JMR7-XGP7-CMFJ fast-xml-parser affected by DoS through entity expansion in DOCTYPE (no expansion limit)

Summary The XML parser can be forced to do an unlimited amount of entity expansion. With a very small XML input, it’s possible to make the parser spend seconds or even minutes processing a single request, effectively freezing the application. Details There is a check in DocTypeReader.js that trie...
