{"id":"UBUNTU-CVE-2021-32052","details":"In Django 2.2 before 2.2.22, 3.1 before 3.1.10, and 3.2 before 3.2.2 (with Python 3.9.5+), URLValidator does not prohibit newlines and tabs (unless the URLField form field is used). If an application uses values with newlines in an HTTP response, header injection can occur. Django itself is unaffected because HttpResponse prohibits newlines in HTTP headers.","modified":"2026-02-04T04:06:58.753401Z","published":"2021-05-06T16:15:00Z","related":["USN-4975-1","USN-5373-1","USN-5373-2"],"upstream":["CVE-2021-32052"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-32052"},{"type":"REPORT","url":"https://www.djangoproject.com/weblog/2021/may/06/security-releases/"},{"type":"REPORT","url":"https://docs.djangoproject.com/en/3.2/releases/security/"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2021/05/06/1"},{"type":"REPORT","url":"https://groups.google.com/forum/#!forum/django-announce"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4975-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5373-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5373-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2021-32052"}],"affected":[{"package":{"name":"python-django","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/python-django@1:1.11.11-1ubuntu1.17?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:1.11.11-1ubuntu1.17"}]}],"versions":["1:1.11.4-1ubuntu1","1:1.11.6-1ubuntu1","1:1.11.9-1ubuntu1","1:1.11.11-1ubuntu1","1:1.11.11-1ubuntu1.1","1:1.11.11-1ubuntu1.2","1:1.11.11-1ubuntu1.3","1:1.11.11-1ubuntu1.4","1:1.11.11-1ubuntu1.5","1:1.11.11-1ubuntu1.6","1:1.11.11-1ubuntu1.7","1:1.11.11-1ubuntu1.8","1:1.11.11-1ubuntu1.9","1:1.11.11-1ubuntu1.10","1:1.11.11-1ubuntu1.11","1:1.11.11-1ubuntu1.12","1:1.11.11-1ubuntu1.13","1:1.11.11-1ubuntu1.14","1:1.11.11-1ubuntu1.15","1:1.11.11-1ubuntu1.16"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"python-django","binary_version":"1:1.11.11-1ubuntu1.17"},{"binary_name":"python-django-common","binary_version":"1:1.11.11-1ubuntu1.17"},{"binary_name":"python3-django","binary_version":"1:1.11.11-1ubuntu1.17"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-32052.json"}},{"package":{"name":"python-django","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/python-django@2:2.2.12-1ubuntu0.7?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.2.12-1ubuntu0.7"}]}],"versions":["1:1.11.22-1ubuntu1","2:2.2.6-1ubuntu1","2:2.2.9-2ubuntu1","2:2.2.10-1","2:2.2.10-1ubuntu1","2:2.2.11-1","2:2.2.12-1","2:2.2.12-1ubuntu0.1","2:2.2.12-1ubuntu0.2","2:2.2.12-1ubuntu0.3","2:2.2.12-1ubuntu0.4","2:2.2.12-1ubuntu0.5","2:2.2.12-1ubuntu0.6"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"python3-django","binary_version":"2:2.2.12-1ubuntu0.7"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-32052.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
