|---|---|---|---|---|---|---|
| CVE-2026-42091 | goshs is a SimpleHTTPServer written in Go. Prior to version 2.0.2, the PUT upload handler (httpserver/updown.go) lacks the CSRF token validation that was added to the POST upload handler during the CVE-2026-40883 fix. Combined with the unconditional Access-Control-Allow-Origin: * on the OPTIONS preflight handler (httpserver/server.go), any website can write arbitrary files to a goshs instance through the victim's browser — bypassing network isolation (e.g. localhost, internal network).

| CVE-2026-40903 | goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.6, goshs has an ArtiPACKED vulnerability. ArtiPACKED can lead to leakage of the GITHUB_TOKEN through workflow artifacts, even though the token is not present in the repository source code. This vulnerability is fixed in 2.0.0-beta.6. | [email protected] | 9.1 | 0.24% | 2026-04-21 | 2026-06-17 |
| CVE-2026-40885 | goshs is a SimpleHTTPServer written in Go. From 2.0.0-beta.4 to 2.0.0-beta.5, goshs leaks file-based ACL credentials through its public collaborator feed when the server is deployed without global basic auth. Requests to .goshs-protected folders are logged before authorization is enforced, and the collaborator websocket broadcasts raw request headers, including Authorization. An unauthenticated observer can capture a victim's folder-specific basic-auth header and replay it to read, upload, overw | [email protected] | 7.7 | 0.31% | 2026-04-21 | 2026-06-17 |
| CVE-2026-40884 | goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.6, goshs contains an SFTP authentication bypass when the documented empty-username basic-auth syntax is used. If the server is started with -b ':pass' together with -sftp, goshs accepts that configuration but does not install any SFTP password handler. As a result, an unauthenticated network attacker can connect to the SFTP service and access files without a password. This vulnerability is fixed in 2.0.0-beta.6. | [email protected] | 9.8 | 0.48% | 2026-04-21 | 2026-06-17 |
| CVE-2026-40883 | goshs is a SimpleHTTPServer written in Go. From 2.0.0-beta.4 to 2.0.0-beta.5, goshs contains a cross-site request forgery issue in its state-changing HTTP GET routes. An external attacker can cause an already authenticated browser to trigger destructive actions such as ?delete and ?mkdir because goshs relies on HTTP basic auth alone and performs no CSRF, Origin, or Referer validation for those routes. This vulnerability is fixed in 2.0.0-beta.6. | [email protected] | 6.1 | 0.14% | 2026-04-21 | 2026-06-17 |
| CVE-2026-40876 | goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.6, goshs contains an SFTP root escape caused by prefix-based path validation. An authenticated SFTP user can read from and write to filesystem paths outside the configured SFTP root, which breaks the intended jail boundary and can expose or modify unrelated server files. The SFTP subsystem routes requests through sftpserver/sftpserver.go into DefaultHandler.GetHandler() in sftpserver/handler.go, which forwards file operations into re | [email protected] | 8.7 | 0.44% | 2026-04-21 | 2026-06-17 |
| CVE-2026-40189 | goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.4, goshs enforces the documented per-folder .goshs ACL/basic-auth mechanism for directory listings and file reads, but it does not enforce the same authorization checks for state-changing routes. An unauthenticated attacker can upload files with PUT, upload files with multipart POST /upload, create directories with ?mkdir, and delete files with ?delete inside a .goshs-protected directory. By deleting the .goshs file itself, the attac | [email protected] | 9.3 | 0.65% | 2026-04-10 | 2026-06-17 |
| CVE-2026-40188 | goshs is a SimpleHTTPServer written in Go. From 1.0.7 to before 2.0.0-beta.4, the SFTP command rename sanitizes only the source path and not the destination, so it is possible to write outside of the root directory of the SFTP. This vulnerability is fixed in 2.0.0-beta.4. | [email protected] | 7.7 | 0.32% | 2026-04-10 | 2026-06-17 |
| CVE-2026-35471 | goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.3, tdeleteFile() missing return after path traversal check. This vulnerability is fixed in 2.0.0-beta.3. | [email protected] | 9.8 | 0.68% | 2026-04-06 | 2026-06-17 |
| CVE-2026-35393 | goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.3, the POST multipart upload directory not sanitized. This vulnerability is fixed in 2.0.0-beta.3. | [email protected] | 9.8 | 0.68% | 2026-04-06 | 2026-06-17 |
| CVE-2026-35392 | goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.3, PUT upload in httpserver/updown.go has no path sanitization. This vulnerability is fixed in 2.0.0-beta.3. | [email protected] | 9.8 | 0.68% | 2026-04-06 | 2026-06-17 |
| CVE-2026-34581 | goshs is a SimpleHTTPServer written in Go. From version 1.1.0 to before version 2.0.0-beta.2, when using the Share Token it is possible to bypass the limited selected file download with all the gosh functionalities, including code exec. This issue has been patched in version 2.0.0-beta.2. | [email protected] | 8.1 | 0.39% | 2026-04-02 | 2026-06-17 |
