7.5HighCVE-2026-54719Gogithub.com/patrickhener · goshs +4 moregoshs: File-based .goshs ACL authorization bypass via the ?bulk zip-download route (unauthenticated read; residual of CVE-2026-40189)goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.1, the httpserver/updown.go bulkDownload handler for ?bulk&file= ZIP downloads did not call findEffectiveACL or applyCustomAuth, allowing unauthenticated reads of files protected only by .goshs folder ACLs and block lists. This issue is fixed in version 2.1.1. This vulnerability exists due to an incomplete fix for CVE-2026-40189.EPSS0.47%9.1CriticalCVE-2026-62325Gogithub.com/patrickhener/goshs · v2 +3 moregoshs SFTP authentication bypass via empty password (incomplete fix of CVE-2026-40884)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.

Prior to 2.1.5, the httpserver/handler.go sendFile handler opened files using a cleaned path but derived the authorization filename from raw req.URL.Path, so a trailing slash could bypass .goshs ACL-file protection and block-list checks. This issue is fixed in version 2.1.5.EPSS0.45%9.1CriticalCVE-2026-64863Gogithub.com/patrickhener · goshs +4 moregoshs --no-delete WebDAV MOVE bypass allows file deletion/overwritegoshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.4, the httpserver/server.go wdGuard handled WebDAV MOVE as a write-only method and did not enforce --no-delete, allowing WebDAV clients to delete or overwrite files via MOVE with Overwrite: T. This issue is fixed in version 2.1.4.EPSS0.63%
