CVE-2026-62325

CRITICAL

goshs SFTP authentication bypass via empty password (incomplete fix of CVE-2026-40884)

Title source: cna
STIX 2.1

Description

goshs is a feature-rich single-binary file server for red teamers and developers. From 2.1.3 until 2.1.4, the sftpserver/sftpserver.go password handler used Username != "" && Password != "", so running goshs with -b 'admin:' -sftp and no -fkf left both SFTP authentication handlers unset and allowed unauthenticated file access. This issue is fixed in version 2.1.4.
