CVE-2026-20198

Cisco Integrated Management Controller Cross-Site Scripting Vulnerability

Published Aug 5, 2026 CVSS 3.1 · 4.8 Medium EPSS < 1% KEV · Not listed

Description

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker to conduct a cross-site scripting (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.
