NCSC-NL published an advisory covering CVE-2026-18851, a missing authorization vulnerability in Ivanti Endpoint Manager Mobile (EPMM). The flaw affects versions prior to 12.10.0.0, 12.9.0.2, and 12.8.0.4, and allows an authenticated user to escalate privileges to an administrative level, likely by bypassing an authorization check on a sensitive function or endpoint. Ivanti has released updated versions that address the issue.
The vulnerability carries a CVSS v3 score of 8.8, reflecting the significant impact of full administrative compromise despite requiring prior authentication. No indication of active exploitation is mentioned in the advisory. Defenders running Ivanti EPMM should prioritize patching to the fixed versions (12.10.0.0, 12.9.0.2, or 12.8.0.4 or later) and review authentication logs and administrative account activity for signs of unauthorized privilege changes, particularly from lower-privileged accounts.
