A vulnerability in the self-service portal of Cisco Duo could allow an unauthenticated, remote attacker to inject arbitrary commands into emails that are sent by the service.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
Description

This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting arbitrary commands into a portion of an email that is sent by the service.
