CVE-2026-20132 Published on April 15, 2026
Cisco Identity Services Engine Multiple Cross-Site Scripting Vulnerabilities
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.
