CVE-2026-4145 is a vulnerability in Lenovo Software Fix where improper neutralization of argument delimiters (CWE-88) can lead to argument injection. This flaw enables a local authenticated user to execute arbitrary code with elevated privileges, potentially compromising system security. The vulnerability was identified internally and is not yet accompanied by an official fix or patch. The CVSS 4.0 vector indicates low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability, but requires local privileges to exploit.

If exploited, this vulnerability allows a local authenticated user to perform arbitrary code execution with elevated privileges, which could lead to full system compromise. The high CVSS score reflects significant potential impact on system confidentiality, integrity, and availability. However, there are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the Lenovo vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, users should monitor Lenovo's security advisories for updates. Until a patch is available, restrict local access to trusted users only and apply the principle of least privilege to limit potential exploitation.
