## Description

Next.js is a React framework for building full-stack web applications. In affected versions if a Next.js application is performing authorization in middleware based on pathname, it was possible for this authorization to be bypassed for pages directly under the application's root directory. For example: \* \[Not affected\] \`https://example.com/\` \* \[Affected\] \`https://example.com/foo\` \* \[Not affected\] \`https://example.com/foo/bar\`. This issue is patched in Next.js \`14.2.15\` and later. If your Next.js application is hosted on Vercel, this vulnerability has been automatically mitigated, regardless of Next.js version. There are no official workarounds for this vulnerability.
