Multiple critical vulnerabilities in Cisco ISE and ISE-PIC, including a remote code execution flaw (CVE-2026-20147, CVSS 9.9) and a path traversal flaw (CVE-2026-20148, CVSS 4.9), allow an authenticated attacker with administrative credentials to execute arbitrary code or perform directory traversal attacks. Cisco has released software updates to address these issues; there are no available workarounds.
Multiple vulnerabilities in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to achieve remote code execution or conduct path traversal attacks on an affected device. To exploit these vulnerabilities, the attacker must have valid administrative credentials. For more information about these vulnerabilities, see the Details section of this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
