CVE-2022-36077Network attack vector

Hashed credential disclosure via delayed file URL check

Published Nov 8, 2022 · Updated Apr 23, 2025

Information exposure in Electron allows remote attackers to obtain hashed NTLM credentials when an application follows a crafted SMB redirect. A cross-scheme file URL check occurs only after Windows begins the SMB connection and its NTLM authentication attempt. The issue requires an Electron application to follow an attacker-controlled redirect; the renderer cannot read the target file.
