      <title>CVE-2021-43803 — Unexpected server crash in Next.js</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2021-43803</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; vercel next.js&lt;/p&gt;
&lt;p&gt;Next.js is a React framework. In versions of Next.js prior to 12.0.5 or 11.1.3, invalid or malformed URLs could lead to a server crash. In order to be affected by this issue, the deployment must use Next.js versions above 11.1.0 and below 12.0.5, Node.js above 15.0.0, and next start or a custom server. Deployments on Vercel are not affected, along with similar environments where invalid requests are filtered before reaching Next.js. Versions 12.0.5 and 11.1.3 contain patches for this issue.&lt;/p&gt;</description>
