Good to know:
Date: August 30, 2021
Next.js is a React framework. Versions of Next.js between 10.0.0 and 11.0.0 contain a cross-site scripting vulnerability. In order for an instance to be affected by the vulnerability, the "next.config.js" file must have "images.domains" array assigned and the image host assigned in "images.domains" must allow user-provided SVG. If the "next.config.js" file has "images.loader" assigned to something other than default or the instance is deployed on Vercel, the instance is not affected by the vulnerability.
