Description
A flaw was found in Vue.js. Within the parseHTML() function of html-parser.ts, there is a regular expression (regex) to check for proper closing tags for HTML. However, due to an improperly written regex, when you pass a script containing long text, it will trigger a regular expression denial of service (ReDoS) attack, which can cause the process to slow down significantly and render the application unavailable.
