"According to its self-reported version, Cisco ISE is affected by a vulnerability.

  - A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow
    an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack 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. (CVE-2026-20076)

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
