CVE-2026-20087: Cisco Integrated Management Controller Cross-Site Scripting Vulnerability

Published Apr 1, 2026
·
Updated

A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information.
