Description

SFTPGo is an SFTP server written in Go. Versions prior to 2.3.5 are subject to Cross-site scripting (XSS) vulnerabilities in the SFTPGo WebClient, allowing remote attackers to inject malicious code. This issue is patched in version 2.3.5. No known workarounds exist.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/drakkan/sftpgo, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/drakkan/sftpgo to 2.3.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cf7g-cm7q-rq7f is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
