Payload is a free and open source headless content management system. Prior to version 3.78.0 in @payloadcms/next, a stored Cross-Site Scripting (XSS) vulnerability existed in the admin panel. An authenticated user with write access to a collection could save content that, when viewed by another user, would execute in their browser. This issue has been patched in version 3.78.0.
