Smart Connect: Authentication Bypass by Spoofing
CVE-2026-6090 is a high-severity authentication bypass by spoofing vulnerability in Smart Connect from Lenovo, with a CVSS 3.1 base score of 7.0 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 09.0.2.003.000 as the first without the flaw, so updating Smart Connect to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.11% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
