Stored XSS in Ivanti Neurons for ITSM

IdentifiersCVE-2026-4914CWE-79· Improper Neutralization of Input…

CVE-2026-4914 is a stored cross-site scripting (XSS) vulnerability in Ivanti Neurons for ITSM (N-ITSM) versions prior to 2025.4. A remote authenticated attacker can inject malicious script into application content that is later rendered by other users. When a victim user accesses the crafted content, the script executes in the context of that user’s session. According to the provided content, successful exploitation allows the attacker to obtain limited information from other user sessions, with potential exposure including session tokens, credentials, or sensitive ITSM data. The issue affects version 2025.3 and earlier releases, including both on-premise and cloud deployments.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation enables cross-session data theft from users who view attacker-controlled stored content. The attacker may obtain limited information from other users’ sessions, potentially including session tokens, credentials, or sensitive ITSM data accessible in the victim’s browser context. The vulnerability has cross-scope impact because attacker-supplied script executes in another user’s session context.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, reduce exposure by limiting access to untrusted or user-supplied content within N-ITSM, restricting which authenticated users can create or modify content rendered by other users, and monitoring for suspicious embedded script or HTML in records and workflow content. Because exploitation requires a victim to view malicious stored content, operational mitigations should focus on minimizing rendering of untrusted content and prioritizing rapid upgrade to 2025.4. No specific vendor-provided workaround beyond patching was included in the provided content.

Remediation

Patch, then assume compromise.

Upgrade Ivanti Neurons for ITSM to version 2025.4, which contains the vendor fix for CVE-2026-4914. For on-premise deployments, Ivanti indicates customers must manually upgrade through the Ivanti License System (ILS). For cloud deployments, the provided content states Ivanti already applied the fixes to cloud environments on December 12, 2025, and cloud customers do not need to take further action.
