## ⚠️ ATTN: this release fixes an ftp/sftp issue with shares

* [GHSA-67rw-2x62-mqqm](https://github.com/9001/copyparty/security/advisories/GHSA-67rw-2x62-mqqm): when a share is created for just one or more files inside a folder, it was possible to use FTP or SFTP to access the other files inside that folder by guessing the filenames
  * so ignore this issue if you did not enable [ftp](https://copyparty.eu/cli/#g-ftp) or [sftp](https://copyparty.eu/cli/#g-sftp) in the server config
* it was not possible to descend into subdirectories in this manner; only the sibling files were accessible
* NOTE: this does NOT affect filekeys; this is specifically regarding the [shr](https://copyparty.eu/cli/#g-shr) global-option
* password-protected shares were not affected through SFTP, only FTP

this release also fixes [GHSA-rcp6-88mm-9vgf](https://github.com/9001/copyparty/security/advisories/GHSA-rcp6-88mm-9vgf) but that one is nothing to worry about
