CVE-2026-20190 Jun 17, 16:17 HIGH NEWS This Week

Information disclosure in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) allows unauthenticated remote attackers to retrieve sensitive data - including hashed credentials - by sending crafted traffic to an affected device. The root cause is missing authorization checks on a protected resource (CWE-285), making this an authentication-bypass-style information leak. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.

CVE-2026-20181 Jun 17, 16:16 CRITICAL NEWS Act Now

Authenticated remote command execution in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) allows administrators to run arbitrary OS commands and escalate to root via a crafted HTTP request. The flaw, tracked as CVE-2026-20181 and reported by Cisco with a CVSS 3.1 score of 9.1 (scope-changed), can also crash single-node deployments and deny network access to unauthenticated endpoints. There is no public exploit identified at time of analysis.

CVE-2026-20147 Apr 15, 16:03 CRITICAL NEWS Act Now

Command injection in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (PIC) allows authenticated administrative attackers to execute arbitrary OS commands, achieving user-level access and privilege escalation to root. In single-node deployments, exploitation can cause a denial of service, disrupting network access for unauthenticated endpoints. No active exploitation has been observed and the low EPSS score suggests lower immediate risk.

CVE-2026-20146 Jul 15, 16:17 MEDIUM This Month

Path traversal in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) allows a remote, authenticated attacker with administrative credentials to read or delete arbitrary files on the underlying operating system via crafted HTTP requests. Successful exploitation could expose sensitive configuration or credential files, or trigger destructive deletion of system files. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the high confidentiality impact and the critical role ISE plays in enterprise network access control make this notable for environments running affected versions.
