Which packages are affected by GHSA-49cc-xrjf-9qf7?

GHSA-49cc-xrjf-9qf7 affects the following packages: github.com/drakkan/sftpgo/v2 (Go), sftpgo (Go). Ecosystems affected: Go.

How do I fix GHSA-49cc-xrjf-9qf7?

Update github.com/drakkan/sftpgo/v2 to 2.6.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-49cc-xrjf-9qf7 is resolved across your whole dependency graph.

How do I detect GHSA-49cc-xrjf-9qf7 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/drakkan/sftpgo/v2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-49cc-xrjf-9qf7 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is GHSA-49cc-xrjf-9qf7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-49cc-xrjf-9qf7 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-49cc-xrjf-9qf7?

GHSA-49cc-xrjf-9qf7 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 50th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-49cc-xrjf-9qf7?

GHSA-49cc-xrjf-9qf7 is classified as Improper Input Validation (CWE-20). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

Impact

One powerful feature of SFTPGo is the ability to have the EventManager execute scripts or run applications in response to certain events. This feature is very common in all software similar to SFTPGo and is generally unrestricted.

However, any SFTPGo administrator with permission to run a script has access to the underlying OS/container with the same permissions as the user running SFTPGo, so they can access the database and server configurations.

This is unexpected for some SFTPGo administrators who think that there is a clear distinction between accessing the system shell and accessing the SFTPGo WebAdmin UI.

Patches

To avoid this confusion, running system commands is now disabled by default, and an allow list has been added so that system administrators configuring SFTPGo must explicitly define which commands are allowed to be configured from the WebAdmin UI.

Workarounds

Allow EventManager to be used only by SFTPGo administrators who also have shell access.
