@vue/server-renderer is vulnerable to Cross-Site Scripting (XSS)

High Risk
This Affects:
@vue/server-rendererTL;DR
During server-side rendering, Vue validates dynamic HTML attribute names with a helper whose unsafe-character set omits the carriage return. When an application binds an object with untrusted property names to an element via v-bind, a key containing a carriage return is written into the rendered markup. Browsers convert the carriage return into a line feed, which splits the single attribute name into several attributes and lets injected event-handler attributes run script on page load. The fix adds the carriage return to the set of characters rejected in attribute names.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you use server-side rendering and bind objects with untrusted property names to HTML elements via v-bind.
