Summary

Copyparty ftp/sftp: Sharing a single file did not fully restrict source-folder access

Details

There was a missing permission-check in the shares feature (the shr global-option).

This vulnerability only applies in the following scenario: * The shares feature is used for the specific purpose of creating a share of just a single file inside a folder * Either the FTP or SFTP server is enabled, and also made publically accessible * If a share is password-protected, then SFTP was not vulnerable unless the sftp-pw global-option was also enabled

Given these conditions, when a user is browsing a share through either FTP or SFTP (not http or https), they can gain read-access to the remaining files inside the shared folder by guessing/bruteforcing the filenames.

It was not possible to descend into subdirectories in this manner; only the sibling files were accessible.

This issue did not affect filekeys or dirkeys.

This vulnerability is CVE-2025-58753 which was previously fixed for HTTP and HTTPS, but not for FTP. The FTPS server did not yet exist at that time.

Severity ?

2.3 (Low)

Vulnerability from cvelistv5 – Published: 2026-03-11 20:14 – Updated: 2026-03-12 19:47

Title

Copyparty ftp/sftp: Sharing a single file did not fully restrict source-folder access

Summary

Copyparty is a portable file server. Prior to 1.20.12, there was a missing permission-check in the shares feature (the shr global-option). This vulnerability only applies when the shares feature is used for the specific purpose of creating a share of just a single file inside a folder or either the FTP or SFTP server is enabled, and also made publicly accessible. Given these conditions, when a user is browsing a share through either FTP or SFTP (not http or https), they can gain read-access to the remaining files inside the shared folder by guessing/bruteforcing the filenames. It was not possible to descend into subdirectories in this manner; only the sibling files were accessible. This vulnerability is similar to CVE-2025-58753 which was previously fixed for HTTP and HTTPS, but not for FTP. The FTPS server did not yet exist at that time. This vulnerability is fixed in 1.20.12.
