OpenManage Enterprise: Authentication Bypass by Spoofing
CVE-2026-91914 is a high-severity authentication bypass by spoofing vulnerability in OpenManage Enterprise from Dell, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version 4.8.0 or later as the first without the flaw, so updating OpenManage Enterprise to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
