FKIE_CVE-2026-3775

Vulnerability from fkie_nvd - Published: 2026-04-01 02:16 - Updated: 2026-06-17 10:44

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

The application's update service, when checking for updates, loads certain system libraries from a search path that includes directories writable by low‑privileged users and is not strictly restricted to trusted system locations. Because these libraries may be resolved and loaded from user‑writable locations, a local attacker can place a malicious library there and have it loaded with SYSTEM privileges, resulting in local privilege escalation and arbitrary code execution.
