# 2026-0727-2202 `v1.20.19` SECURITY: fix FTP upload outside volume
## ⚠️ ATTN: this release fixes a vulnerability in FTP and FTPS (not SFTP)
the FTP-server (default-disabled) would allow uploading to any folder that the copyparty process had permission to write to, but with certain limitations; see [GHSA-phv8-wgjp-g4p9](https://github.com/9001/copyparty/security/advisories/GHSA-phv8-wgjp-g4p9)

* [v1.20.17 (2026-07-06)](https://github.com/9001/copyparty/releases/tag/v1.20.17) fixed a vuln when a volume has both filekeys and dirkeys enabled
