CVE-2018-10189: Mautic

High severity, CVSS 7.5. EPSS: 1.1% chance of exploitation in the next 30 days.

An issue was discovered in Mautic 1.x and 2.x before 2.13.0. It is possible to systematically emulate tracking cookies per contact due to tracking the contact by their auto-incremented ID. Thus, a third party can manipulate the cookie value with +1 to systematically assume being tracked as each contact in Mautic. It is then possible to retrieve information about the contact through forms that have progressive profiling enabled.

Affected products

• Mautic Mautic: from 1.0.0, up to and including 1.4.1; from 2.0.0, before 2.13.0 (fixed in 2.13.0)
