Tracked as <strong><a href="https://nvd.nist.gov/vuln/detail/CVE-2026-76460" target="_blank" rel="noopener noreferrer nofollow ugc">CVE-2026-76460</a></strong> with a <strong>CVSS score of 10.0</strong>, the flaw allows an unauthenticated, remote attacker to bypass authentication.</p>
<p dir="auto">According to Cisco, the issue stems from insufficient authentication control on an API endpoint. This means an attacker could potentially gain access without valid credentials, making it a critical risk for organizations relying on ISE for network access control.</p>
<ul>
<li><strong>Affected product:</strong> Cisco Identity Services Engine (ISE)</li>
<li><strong>Vulnerability type:</strong> Authentication bypass</li>
<li><strong>Severity:</strong> CVSS 10.0 (maximum)</li>
<li><strong>Exploitation status:</strong> Active attacks observed</li>
<li><strong>Attack vector:</strong> Remote, unauthenticated</li>
</ul>
<p dir="auto">Cisco has not yet provided specific patch details or workarounds in the available information, but given the active exploitation and maximum severity, administrators should treat this as an urgent priority. Monitor official Cisco advisories for updates and mitigation guidance.</p>
