Cross-site Scripting (XSS)

preact-render-to-string is a library that renders JSX to an HTML string, with support for Preact components.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) when spread attributes in the ssr files are unsanitized and can therefore be attack vectors for untrusted user input.
