Cisco Identity Services Engine vulnerabilities
16 known CVE vulnerabilities in Cisco Identity Services Engine, translated and rated.
- CVE-2026-76460CriticalActively exploited
A vulnerability in the API of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to bypass authentication. This is due to insufficient authentication control on an API endpoint. An attacker could send a crafted request to gain unauthorized access to the device by bypassing the web-based management interface.
- CVE-2026-20284Critical
A vulnerability in the SXP REST API of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks. This is due to insufficient validation of user-supplied input in REST API calls. A successful exploit could allow the attacker to view or modify data on the underlying database, and in single-node deployments could cause a DoS condition.
- CVE-2026-20237Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to improper input validation issues (CWE-20). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20211Critical
Vulnerability in Cisco ISE allows an authenticated remote attacker with high-privileged admin credentials to execute arbitrary commands on the underlying OS. It is due to insecure deserialization of Java objects. Single-node deployments may experience DoS.
- CVE-2026-20194Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to incorrect resource transfer between spheres (CWE-669). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20192Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to improper access control issues (CWE-284). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20176Critical
Vulnerability in Cisco ISE allows an authenticated remote attacker with high-privileged admin credentials to execute arbitrary commands on the underlying OS. It is due to insufficient validation of user-supplied input. Single-node deployments may experience DoS.
- CVE-2026-20130Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to improper neutralization of special elements (CWE-74). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20186Critical
A vulnerability in Cisco Identity Services Engine (ISE) allows an authenticated remote attacker to execute arbitrary commands on the underlying OS. The attacker needs at least Read Only Admin credentials and sends a crafted HTTP request.
- CVE-2026-20180Critical
A vulnerability in Cisco Identity Services Engine (ISE) allows an authenticated remote attacker to execute arbitrary commands on the underlying OS. The attacker needs at least Read Only Admin credentials and sends a crafted HTTP request.
- CVE-2026-20146Medium
A vulnerability in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) allows an authenticated remote attacker to perform path traversal attacks on the underlying operating system. The attacker can read or delete arbitrary files by sending a crafted HTTP request.
- CVE-2026-20136Medium
A vulnerability in the CLI of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) allows an authenticated local attacker with administrative privileges to perform command injection on the underlying OS and elevate privileges to root. The issue is due to insufficient input validation.
- CVE-2026-20132Medium
Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) allow an authenticated remote attacker with administrative write privileges to conduct stored XSS or reflected XSS attacks against a user of the interface. These issues stem from insufficient sanitization of user-supplied data stored in web pages.
- CVE-2025-20131Medium
A vulnerability in the GUI of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker with administrative privileges to upload files to an affected device. This is due to improper validation of the file copy function, enabling arbitrary file uploads.
- CVE-2025-20205Medium
The web-based management interface of Cisco ISE guest portals has XSS vulnerabilities. An authenticated attacker with administrative credentials can inject malicious code into specific pages, leading to script execution or access to sensitive data.
- CVE-2025-20204Medium
The web-based management interface of Cisco ISE guest portals has XSS vulnerabilities. An authenticated attacker with administrative credentials can inject malicious code into specific pages, leading to script execution or access to sensitive data.
