CVE-2026-109412 Overview
CVE-2026-109412 is an exposed dangerous endpoint vulnerability in Ivanti Neurons Patch for Intune. A remote authenticated attacker can abuse the endpoint to leak sensitive authentication information. The weakness is classified under CWE-749: Exposed Dangerous Method or Function.
The vulnerability is network-reachable and requires only low-privileged authenticated access. Successful exploitation compromises confidentiality, integrity, and availability across trust boundaries, which places this flaw at the top of Ivanti's October 2026 advisory cycle.
Critical Impact
An authenticated remote attacker can harvest authentication material from Ivanti Neurons Patch for Intune, enabling credential theft and downstream lateral movement across tenant and management boundaries.
Affected Products
- Ivanti Neurons Patch for Intune (see Ivanti Security Advisory October 2026 for fixed versions)

Technical Details for CVE-2026-109412
Vulnerability Analysis
Ivanti Neurons Patch for Intune exposes an application endpoint that was not intended to be reachable by low-privileged users. When invoked, the endpoint returns authentication-related data that should remain internal to the service. An attacker holding any authenticated session can call the endpoint and retrieve credential material tied to the Intune patching workflow.
Because the vulnerability crosses a security scope boundary, leaked credentials typically grant access beyond the attacker's original privilege level. This creates a direct path from a low-tier account to administrative control of the patch management workflow and the Intune-managed endpoints it governs.
Root Cause
The root cause maps to [CWE-749], where a product exposes a method or endpoint that performs a privileged action without adequate authorization checks. In this case, the endpoint discloses authentication secrets rather than enforcing least-privilege access.
Attack Vector
Exploitation requires network access to the Ivanti Neurons Patch for Intune management interface and a valid low-privileged account. No user interaction is required. Attackers typically chain this flaw with credential-replay techniques to pivot into higher-value identities after harvesting the leaked authentication information. No public proof-of-concept or in-the-wild exploitation has been reported at the time of publication.
Technical specifics on the vulnerable endpoint are restricted. Refer to the Ivanti Security Advisory October 2026 for vendor-supplied details.
Detection Methods for CVE-2026-109412
Indicators of Compromise
- Unexpected authenticated HTTP requests to administrative or internal endpoints of the Ivanti Neurons Patch for Intune service.
- Authentication tokens or service credentials appearing in response bodies captured by web proxies or application logs.
- Reuse of Neurons service account credentials from unfamiliar source IP addresses or at unusual times.
Detection Strategies
- Review Ivanti Neurons application logs for low-privileged accounts invoking endpoints historically used only by administrators or service identities.
- Correlate authentication events in Entra ID and on-premises directories for Neurons service accounts to spot sudden geographic or device changes.
- Alert on anomalous volumes of successful authentications originating from a single Neurons user account within short time windows.
Monitoring Recommendations
- Forward Ivanti Neurons Patch for Intune logs into a central analytics pipeline such as Singularity Data Lake for retention and cross-source correlation.
- Enable identity telemetry on all accounts with access to the Neurons console and treat credential reuse events as high-severity signals.
- Monitor outbound traffic from the Neurons host for connections to attacker-controlled infrastructure following suspicious endpoint calls.
How to Mitigate CVE-2026-109412
Immediate Actions Required
- Apply the fixed version listed in the Ivanti Security Advisory October 2026 without delay.
- Rotate any service account credentials, API tokens, and client secrets used by Ivanti Neurons Patch for Intune after patching.
- Audit recent authentication logs for the Neurons application and investigate any low-privileged account that accessed administrative endpoints.
Patch Information
Ivanti released fixes as part of its October 2026 security advisory cycle. Administrators should consult the Ivanti Security Advisory October 2026 for the exact fixed build numbers and update procedures.
Workarounds
- Restrict network access to the Ivanti Neurons Patch for Intune management interface to trusted administrative networks until patching completes.
- Enforce multi-factor authentication on all accounts able to authenticate to the Neurons service to raise the cost of credential reuse.
- Temporarily reduce the number of accounts with access to the Neurons console and remove any dormant or shared identities.
