@inertiajs/react is vulnerable to Cross-Site Scripting (XSS)
59
Medium Risk
This Affects:
@inertiajs/reactTL;DR
The Head component renders the title prop into a <title> element during server-side rendering without HTML-escaping its value. An application that passes attacker-controlled data as the page title lets an attacker close the title element early and inject markup such as </title><script> into the server-rendered HTML response. Before the fix this allows arbitrary script execution in the victim's browser in the application origin. The fix escapes the title content before it is written into the SSR <title> element.
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 with Head titles derived from untrusted input.
