| Description: | | Vercel Next.js is an open-source web application framework developed by Vercel that supports server-side rendering and static generation. Vercel Next.js versions 13.4.0 up to but not including 15.5.24, and versions 16.0.0 up to but not including 16.3.3, contain a path traversal vulnerability. This vulnerability arises from improperly escaping backslashes in route segments when constructing incremental cache paths on Windows servers (involving the escape-path-delimiters.ts and file-system-cache.ts files), allowing remote requests to traverse outside the intended cache root directory via encoded Windows path separators, exposing private build data (including server reference manifest encryption keys), which may in turn lead to remote code execution. |
