CVE-2026-20160: Cisco smart software manager on-prem exposure of resource to wrong sphere vulnerability

Cisco · Smart Software Manager On Prem

A vulnerability in Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an unauthenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected SSM On-Prem host. This vulnerability is due to the unintentional exposure of an internal service. An attacker could exploit this vulnerability by sending a crafted request to the API of the exposed service. A successful exploit could allow the attacker to execute commands on the underlying operating system with root-level privileges.
