CVE-2019-16056

CVE-2019-16056, high severity (CVSS 7.5): 3 tracked apps concerned, all fixed or indeterminable on their current version.

Severity (CVSS): 7.5
Exploitation: 5.4 %
Tracked apps: 3
Still exposed: 0

Published on 2019-09-06

An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An application that uses the email module and implements some kind of checks on the From/To headers of a message could be tricked into accepting an email address that should be denied. An attack may be the same as in CVE-2019-11340; however, this CVE applies to Python more generally.
