CWE: NVD-CWE-Other \u2014 Other
NVD is only using a subset of CWE for mapping instead of the entire CWE, and the weakness type is not covered by that subset.

Code:
    public function testRender()
    {
        $kernel = self::bootKernel();
        /** @var Environment $twig */
        $twig = self::getContainer()->get('twig');
        $stack = self::getContainer()->get('request_stack');
        $cacheDir = $kernel->getContainer()->getParameter('kernel.cache_dir');
        $converter = new MPdfConverter((new FileHelperFactory($this))->create(), $cacheDir);
        $request = new Request();
        $request->setLocale('en');
        $stack->push($request);

        $sut = new PDFRenderer($twig, $converter, $this->createMock(ProjectStatisticService::class));

        $response = $this->render($sut);

        $prefix = date('Ymd');
        $this->assertEquals('application/pdf', $response->headers->get('Content-Type'));
        $this->assertEquals('attachment; filename=' . $prefix . '-Customer_Name-project_name.pdf', $response->headers->get('Content-Disposition'));

        $this->assertNotEmpty($response->getContent());
    }
