{"id":"UBUNTU-CVE-2019-19844","details":"Django before 1.11.27, 2.x before 2.2.9, and 3.x before 3.0.1 allows account takeover. A suitably crafted email address (that is equal to an existing user's email address after case transformation of Unicode characters) would allow an attacker to be sent a password reset token for the matched user account. (One mitigation in the new releases is to send password reset tokens only to the registered user email address.)","modified":"2026-02-04T03:02:43.522617Z","published":"2019-12-18T00:00:00Z","related":["USN-4224-1","USN-6722-1"],"upstream":["CVE-2019-19844"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-19844"},{"type":"REPORT","url":"https://www.djangoproject.com/weblog/2019/dec/18/security-releases/"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4224-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6722-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-19844"}],"affected":[{"package":{"name":"python-django","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/python-django@1.6.11-0ubuntu1.3+esm7?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.11-0ubuntu1.3+esm7"}]}],"versions":["1.5.4-1ubuntu1","1.6-1","1.6.1-1","1.6.1-2","1.6.1-2ubuntu0.1","1.6.1-2ubuntu0.2","1.6.1-2ubuntu0.3","1.6.1-2ubuntu0.4","1.6.1-2ubuntu0.5","1.6.1-2ubuntu0.6","1.6.1-2ubuntu0.8","1.6.1-2ubuntu0.9","1.6.1-2ubuntu0.10","1.6.1-2ubuntu0.11","1.6.1-2ubuntu0.12","1.6.1-2ubuntu0.13","1.6.1-2ubuntu0.14","1.6.1-2ubuntu0.15","1.6.1-2ubuntu0.16","1.6.11-0ubuntu1","1.6.11-0ubuntu1.1","1.6.11-0ubuntu1.2","1.6.11-0ubuntu1.3","1.6.11-0ubuntu1.3+esm1","1.6.11-0ubuntu1.3+esm2","1.6.11-0ubuntu1.3+esm3","1.6.11-0ubuntu1.3+esm4","1.6.11-0ubuntu1.3+esm5","1.6.11-0ubuntu1.3+esm6"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.11-0ubuntu1.3+esm7","binary_name":"python-django"}],"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-19844.json"}},{"package":{"name":"python-django","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/python-django@1.8.7-1ubuntu5.11?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.7-1ubuntu5.11"}]}],"versions":["1.7.9-1ubuntu5","1.8.5-2ubuntu1","1.8.7-1ubuntu1","1.8.7-1ubuntu2","1.8.7-1ubuntu3","1.8.7-1ubuntu4","1.8.7-1ubuntu5","1.8.7-1ubuntu5.1","1.8.7-1ubuntu5.2","1.8.7-1ubuntu5.4","1.8.7-1ubuntu5.5","1.8.7-1ubuntu5.6","1.8.7-1ubuntu5.7","1.8.7-1ubuntu5.8","1.8.7-1ubuntu5.9","1.8.7-1ubuntu5.10"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.7-1ubuntu5.11","binary_name":"python-django"},{"binary_version":"1.8.7-1ubuntu5.11","binary_name":"python-django-common"},{"binary_version":"1.8.7-1ubuntu5.11","binary_name":"python3-django"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-19844.json"}},{"package":{"name":"python-django","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/python-django@1:1.11.11-1ubuntu1.6?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:1.11.11-1ubuntu1.6"}]}],"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"],"ecosystem_specific":{"binaries":[{"binary_version":"1:1.11.11-1ubuntu1.6","binary_name":"python-django"},{"binary_version":"1:1.11.11-1ubuntu1.6","binary_name":"python-django-common"},{"binary_version":"1:1.11.11-1ubuntu1.6","binary_name":"python3-django"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-19844.json"}},{"package":{"name":"python-django","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/python-django@2:2.2.9-2ubuntu1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.2.9-2ubuntu1"}]}],"versions":["1:1.11.22-1ubuntu1","2:2.2.6-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"2:2.2.9-2ubuntu1","binary_name":"python3-django"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-19844.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"high"}]}
