CVE-2026-49244

Summary

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.
