VLAI?
Summary
SFTPGo Vulnerable to Path Traversal and Permission Bypass via Path Normalization Discrepancy
Details

Impact

In SFTPGo versions prior to 2.7.1, a path normalization discrepancy between the protocol handlers and the internal Virtual Filesystem routing can lead to an authorization bypass. An authenticated attacker can craft specific file paths to bypass folder-level permissions or escape the boundaries of a configured Virtual Folder.

Patches

This issue has been addressed in SFTPGo version 2.7.1. The fix introduces strict edge-level path normalization, ensuring that all protocol inputs are fully sanitized and resolved to canonical POSIX paths before any routing or permission evaluations occur.
