CVE-2026-20132: Cisco Identity Services Engine

Medium severity, CVSS 4.8. EPSS: 0.2% chance of exploitation in the next 30 days.

Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker with administrative write privileges to conduct a stored cross-site scripting (XSS) attack or a reflected XSS attack against a user of the web-based management interface of an affected device. These vulnerabilities are due to insufficient sanitization of user-supplied data that is stored in the web page. An attacker could exploit these vulnerabilities by convincing a user of the interface to click a specific link or view an affected web page. The injected script code may be executed in the context of the web-based management interface or allow the attacker to access sensitive browser-based information.

Affected products

• Cisco Identity Services Engine: before 3.2.0 (fixed in 3.2.0); version 3.2.0 only; version 3.3.0 only; version 3.4.0 only
