CVE-2019-19844: Canonical Ubuntu Linux

Critical severity, CVSS 9.8. EPSS: 53.6% chance of exploitation in the next 30 days.

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.)

Affected products

• Canonical Ubuntu Linux: version 16.04 only; version 18.04 only; version 19.04 only; version 19.10 only
• Djangoproject Django: before 1.11.27 (fixed in 1.11.27); from 2.2, before 2.2.9 (fixed in 2.2.9); version 3.0 only
