CVE-2026-20210

Cisco Catalyst SD-WAN Manager Privilege Escalation Vulnerability

Published May 14, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed

Description

A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an authenticated, remote attacker with read-only permissions to modify configurations and perform unauthorized actions on an affected system.

This vulnerability exists because of a failure to redact sensitive information within device configurations and templates. An attacker could exploit this vulnerability by elevating their read-only permissions to those of a high-privileged user. A successful exploit could allow the attacker to access or modify configuration settings within Cisco Catalyst SD-WAN Manager as a high-privileged user.

Description		A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an authenticated, remote attacker with read-only permissions to modify configurations and perform unauthorized actions on an affected system. This vulnerability exists because of a failure to redact sensitive information within device configurations and templates. An attacker could exploit this vulnerability by elevating their read-only permissions to those of a high-privileged user.
