CVE-2026-53632: Vitejs Launch-Editor

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

launch-editor allows users to open files with line numbers in editor from Node.js. Prior to 2.14.1, the launch-editor NPM package accesses arbitrary paths including Windows UNC paths. When a UNC path is opened, Windows automatically attempts NTLM authentication to the remote host, causing the user’s NTLMv2 password hash to be leaked to an attacker-controlled SMB server. This can result in credential compromise through offline hash cracking. This vulnerability is fixed in 2.14.1.

Affected products

• Vitejs Launch-Editor: before 2.14.1 (fixed in 2.14.1)
• Vitejs Vite: from 8.0.0, before 8.0.16 (fixed in 8.0.16); from 7.0.0, before 7.3.5 (fixed in 7.3.5); before 6.4.3 (fixed in 6.4.3)
• Vitejs Vite-Plus: before 0.1.24 (fixed in 0.1.24)
