CVE-2026-1340 is a critical vulnerability identified in Ivanti Endpoint Manager Mobile, classified under CWE-94, which relates to improper control of code generation, commonly known as code injection. This vulnerability allows an unauthenticated remote attacker to inject and execute arbitrary code on the affected system. The root cause is the failure of the application to properly validate or sanitize input that is used in code generation or execution contexts, enabling attackers to craft malicious payloads that the system executes. The vulnerability does not require any authentication or user interaction, making it highly exploitable remotely over the network. The CVSS v3.1 base score of 9.8 reflects the criticality, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), meaning successful exploitation could lead to full system compromise, data theft, or disruption of services. Ivanti Endpoint Manager Mobile is a widely used enterprise mobile device management (MDM) solution, which manages and secures mobile endpoints across organizations. Exploitation of this vulnerability could allow attackers to bypass security controls, deploy malware, or pivot within enterprise networks. Although no public exploits or patches are currently available, the vulnerability is published and should be treated as a zero-day risk. Organizations relying on this product must prepare for imminent exploitation attempts and prioritize mitigation strategies.

For European organizations, the impact of CVE-2026-1340 is substantial due to the critical role Ivanti Endpoint Manager Mobile plays in managing and securing mobile endpoints. Successful exploitation could lead to unauthorized access to sensitive corporate data, disruption of mobile device management services, and potential lateral movement within corporate networks. This can affect industries with high mobile workforce dependency such as finance, healthcare, government, and critical infrastructure. The loss of confidentiality can expose personal and corporate data, while integrity and availability impacts could disrupt business operations and compliance with GDPR and other regulations. The unauthenticated nature of the vulnerability increases the risk of widespread attacks, potentially targeting multiple organizations simultaneously. Additionally, the lack of current patches means organizations must rely on compensating controls, increasing operational complexity and risk. The threat could also undermine trust in mobile device management solutions, affecting broader IT security postures.

1. Immediate monitoring of network traffic and logs for unusual or unauthorized access attempts targeting Ivanti Endpoint Manager Mobile. 2. Implement strict network segmentation and firewall rules to limit access to the management platform only to trusted administrative networks. 3. Employ application-layer firewalls or intrusion prevention systems (IPS) capable of detecting and blocking code injection attempts. 4. Restrict administrative interfaces to VPN or zero-trust access models to reduce exposure. 5. Regularly audit and review configurations and permissions within the Ivanti Endpoint Manager Mobile environment to minimize attack surface. 6. Prepare incident response plans specifically for potential exploitation scenarios involving this vulnerability. 7. Stay alert for official patches or updates from Ivanti and apply them immediately upon release. 8. Consider temporary alternative mobile device management solutions or enhanced endpoint protection until the vulnerability is remediated. 9. Educate IT and security teams about the vulnerability specifics to ensure rapid detection and response. 10. Collaborate with Ivanti support and threat intelligence communities for emerging exploit information and mitigation best practices.
