CyberRota Analysis
AI-GeneratedThe public web-client partial ZIP download endpoint in SFTPGo versions 2.2.0 to 2.7.3 is vulnerable to improper validation of client-supplied file entries, allowing unauthenticated users to access files outside the intended shared directory. This flaw can lead to unauthorized disclosure of sensitive file contents. Organizations using affected versions should prioritize upgrading to version 2.7.3 to mitigate this risk.

Original NVD Description
SFTPGo is an open source, event-driven file transfer solution. From 2.2.0 until 2.7.3, the public web-client partial ZIP download endpoint for a browsable share validates client-supplied files entries with a raw byte-prefix comparison rather than a directory-boundary-aware check. An unauthenticated requester who can reach a public share can select a canonical path outside the shared directory when the target path begins with the shared directory's name, such as a sibling path that shares the same prefix. The endpoint then includes the out-of-scope file in the generated download, disclosing its contents. This issue is fixed in version 2.7.3.
