Answer in brief
CVE-2026-20220 records a Medium severity (CVSS 6.3) vulnerability in Cisco Crosswork Network Controller Remote Code Execution Vulnerability. The current sources do not mark it as known exploited. The current feed maps Cisco/Cisco Crosswork Network Change Automation (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 6.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A vulnerability in the web-based management interface of Cisco Crosswork Network Controller could allow an authenticated, remote attacker to execute arbitrary commands on an affected device. This vulnerability is due to insufficient input validation in the configuration template engine of the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system in limited areas of the file system. This vulnerability affects only areas of the operating system for which the template user has write permissions. To exploit this vulnerability, the attacker must have valid template user credentials with write permissions. Template users with read permissions cannot exploit this vulnerability.
