CVE-2026-62325 is an authentication bypass vulnerability in goshs, a single-binary file server for red teamers and developers. It affects versions 2.1.3 through 2.1.3, and is fixed in 2.1.4. The flaw is in the SFTP password-handler logic in sftpserver/sftpserver.go, which used the condition Username != "" && Password != "". When goshs was started with SFTP enabled, basic authentication configured with a username and an empty password, and without a public-key authentication handler configured, both SFTP authentication handlers could remain unset. In that state, the SFTP service permitted unauthenticated access to the exposed file service. The issue is classified as missing authentication for a critical function.
