CVE-2026-20047 (GCVE-0-2026-20047)

Vulnerability from cvelistv5 – Published: 2026-01-15 16:32 – Updated: 2026-02-26 15:04

Title

Cisco Identity Services Engine Cross-Site Scripting Vulnerability

Summary

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid administrative credentials.
