CVE-2026-4913 Ivanti CVE debrief

Who should care

Defenders responsible for Ivanti N-ITSM deployments, especially those with remote authenticated users, should assess exposure and prioritize verification and remediation efforts.

Why it matters

CVE-2026-4913 is a medium-severity vulnerability affecting Ivanti N-ITSM, allowing remote authenticated attackers to retain access after account disablement. Defenders should prioritize verification, assessment, and remediation efforts.

• Verify exposure in Ivanti N-ITSM deployments
• Assess potential impact on remote authenticated users
• Implement compensating controls to monitor and limit access

Technical summary

The vulnerability is caused by improper protection of an alternate path in Ivanti N-ITSM before version 2025.4. This allows a remote authenticated attacker to retain access when their account has been disabled. The improper protection of alternate paths enables attackers to bypass normal access controls. Affected deployments should verify exposure and implement compensating controls to monitor and limit access for remote authenticated users until version 2025.4 or a patch is applied.

Defensive priority

Defenders should prioritize verifying exposure in Ivanti N-ITSM deployments, especially for remote authenticated users, and assess the need for compensating controls until version 2025.4 or a patch is applied.

Recommended defensive actions

• Verify Ivanti N-ITSM version and apply patch or upgrade to version 2025.4 or later
• Assess exposure and potential impact on remote authenticated users
• Implement compensating controls to monitor and limit access for remote authenticated users
