SFTPGo Vulnerable to Path Traversal and Permission Bypass via Path Normalization Discrepancy

CVE-2026-30914GHSA-x8qh-7475-c5mp

What to do

Partial vendor fix. Follow the primary source's mitigation guidance and check back for a fix.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2026-30914

Advisory: SFTPGo Vulnerable to Path Traversal and Permission Bypass via Path Normalization Discrepancy
IDs: CVE-2026-30914, GHSA-x8qh-7475-c5mp
Record: https://patchnext.com/advisories/cve-2026-30914 (revision 1, source checked 26 Oct 2026, 15:18 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: github.com/drakkan/sftpgo/v2 2.7.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/drakkan/sftpgo/v2: affected <= 2.7.0; fixed in 2.7.1
- Go github.com/drakkan/sftpgo: affected <= 1.2.2

## Suggested inspection (read-only)
- Go github.com/drakkan/sftpgo/v2: check the installed version with your package manager.
- Go github.com/drakkan/sftpgo: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/drakkan/sftpgo/v2, github.com/drakkan/sftpgo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-x8qh-7475-c5mp (GitHub-reviewed advisory GHSA-x8qh-7475-c5mp lists affected ranges: Go github.com/drakkan/sftpgo/v2 >=0 =0 <=1.2.2)
