What is CVE-2016-4972?

OpenStack Murano, including its dashboard and the python-muranoclient, suffers from vulnerabilities due to improper handling of YAML loaders. This flaw enables remote attackers to design malicious YAML tags that can instantiate arbitrary Python objects. When exploited, this could lead to the execution of arbitrary code during the processing of UI definitions in Murano packages, posing significant risks to affected systems.
