CVE-2026-66064 Medium · 5.3 CWE-41 Jul 28, 2026

goshs has ACL Bypass & Path Traversal

goshs is a feature-rich single-binary file server for red teamers and developers. 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.

CVE-2026-66063 Medium · 6.5 CWE-22 Jul 28, 2026

goshs has a Path Traversal issue

goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.5, the httpserver/updown.go multipart upload handler split part.FileName() on / but did not reject .., allowing an unauthenticated upload with filename .. to create a file outside the served tree. This issue is fixed in version 2.1.5.

CVE-2026-64863 Critical · 9.1 CWE-284 Jul 28, 2026

goshs --no-delete WebDAV MOVE bypass allows file deletion/overwrite

goshs 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.

CVE-2026-62325 Critical · 9.1 CWE-306 Jul 28, 2026

goshs 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. This issue is fixed in version 2.1.4.

CVE-2026-54719 High · 7.5 CWE-862 Jul 28, 2026

goshs: 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.
