What is CVE-2018-16396?

A tainting vulnerability exists in Ruby prior to version 2.6.0-preview3 that fails to appropriately mark certain unpacked strings as tainted. This lack of tainting can lead to potential security risks, as it allows data that should be considered unsafe to pass through the system unchecked. Versions of Ruby affected include 2.3.8 and earlier, 2.4.x before 2.4.5, and 2.5.x before 2.5.2. Remediation is imperative to ensure that tainted data is correctly identified and handled.
