Next.js has cross-site scripting in beforeInteractive scripts with untrusted input

### Impact Applications that use `beforeInteractive` scripts together with untrusted content can be vulnerable to cross-site scripting. In affected versions, serialized script content was not escaped safely before being embedded into the document, which could allow attacker-controlled input to break out of the intended script context and execute arbitrary JavaScript in a visitor's browser. ### Fix We now HTML-escape serialized `beforeInteractive` script content before embedding it into the page, preventing attacker-controlled content from breaking out of the inline script boundary. ### Workarounds If you cannot upgrade immediately, do not pass untrusted data into `beforeInteractive` scripts. If that pattern is unavoidable, sanitize or escape the content before embedding it.
