2026-001: Critical vulnerabilities in Ivanti EPMM

CVE-2026-1340 is a code injection flaw (CWE-94) in Ivanti Endpoint Manager Mobile (EPMM), Ivanti's enterprise mobile device management platform, that permits unauthenticated remote code execution. Because the flaw is network-reachable and requires no privileges or user interaction (AV:N/AC:L/PR:N/UI:N), a remote attacker can send a crafted request to a vulnerable EPMM server and execute arbitrary code, with high impact to confidentiality, integrity, and availability. Any organization operating an affected EPMM server is affected, especially those exposing the management or device-enrollment interface to the internet. The flaw was added to CISA's KEV catalog on 2026-04-08 with an 86.2% probability of exploitation within 30 days; news reporting describes active zero-day attacks against EPMM (alongside related CVE-2026-6973), including a confirmed Dutch government incident exposing employee contact data, while ransomware use remains unconfirmed. A large share of observed exploit traffic has been traced to a single IP address on bulletproof hosting infrastructure.

Do: Apply Ivanti's patched EPMM release per the vendor advisory immediately and verify the fix on any internet-facing EPMM portal; US federal agencies must follow BOD 22-01 mitigation deadlines. Until patched, restrict EPMM portal access to trusted networks/VPNs and review access logs for suspicious requests or unrecognized source IPs, noting that much exploit activity has originated from a single bulletproof-hosting IP.
