CVE-2026-1281: Ivanti Endpoint Manager Mobile (EPMM) Critical Vulnerability

Severity: Critical | CVSS 3.1: 9.8 | Published: 2026-01-29 | KEV Added: 2026-01-29

What is CVE-2026-1281?

A code injection in Ivanti Endpoint Manager Mobile allowing attackers to achieve unauthenticated remote code execution.

Technical Analysis

Weakness Classification

This vulnerability is classified as CWE-94, Code Injection. The application allows user input to be interpreted as code, giving an attacker the ability to execute arbitrary code within the application context.

Attack Vector Breakdown

Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Unchanged
Confidentiality: High
Integrity: High
Availability: High

Impact Analysis

This vulnerability is exploitable over the network, meaning any system reachable via the internet or internal network is potentially at risk without physical access. The attack complexity is low, requires no special privileges, and needs no user interaction, making it straightforward to exploit at scale. Successful exploitation can result in full confidentiality breach (complete data disclosure), complete integrity compromise (data modification or code execution), total availability loss (denial of service). The application allows user input to be interpreted as code, giving an attacker the ability to execute arbitrary code within the application context.

Exploitation Probability (EPSS): 81.2% chance of exploitation in the next 30 days (100th percentile). This places the vulnerability in the highest risk tier, immediate action is critical.

Exploit Availability

Public exploit code or proof-of-concept is available for CVE-2026-1281. This significantly increases the risk of exploitation, as attackers can use or adapt existing exploit code rather than developing their own. A public exploit reference has been identified. Organizations should treat this as an urgent patching priority.

Is CVE-2026-1281 being exploited?

Yes. CVE-2026-1281 is listed in CISA's Known Exploited Vulnerabilities (KEV) catalog, restricted to CVEs with confirmed active exploitation in the wild. CISA added this vulnerability on 2026-01-29. Inclusion in KEV triggers the patching mandate under BOD 22-01 for U.S. federal civilian agencies, with a remediation deadline of 2026-02-01. Additionally, public exploit code is available, which lowers the barrier for attackers.

How to fix CVE-2026-1281

Apply the security patch from the Ivanti download portal. For Ivanti EPMM (MobileIron), apply the RPM update. For Ivanti Connect Secure/Policy Secure, import the patch through the admin console. Follow the advisory for interim mitigation steps such as XML filtering or access restrictions. Check the Ivanti Security Advisories page for the specific patch or update. CISA's Known Exploited Vulnerabilities catalog requires U.S. federal agencies to remediate this vulnerability by the due date shown below under Binding Operational Directive 22-01. Private organizations should treat KEV entries as priority-one patches because active exploitation has been confirmed in the wild.
