HIGH 7.5REMOTEUPGRADE

CVE-2018-10189 is a high-severity flaw (CVSS 7.5) affecting mautic. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

Why this priority

High severity
Remotely exploitable, no login, no user action
