How severe is GHSA-6943-qr24-82vx?

No CVSS score has been assigned to GHSA-6943-qr24-82vx yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-6943-qr24-82vx?

GHSA-6943-qr24-82vx affects the following packages: github.com/drakkan/sftpgo/v2 (Go). Ecosystems affected: Go.

How do I fix GHSA-6943-qr24-82vx?

Update github.com/drakkan/sftpgo/v2 to 2.6.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6943-qr24-82vx is resolved across your whole dependency graph.

How do I detect GHSA-6943-qr24-82vx 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-6943-qr24-82vx 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-6943-qr24-82vx actively exploited in the wild?

No public exploit code has been indexed for GHSA-6943-qr24-82vx 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-6943-qr24-82vx?

GHSA-6943-qr24-82vx has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 35th 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-6943-qr24-82vx?

GHSA-6943-qr24-82vx is classified as Broken Cryptographic Algorithm (CWE-327). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-6943-qr24-82vx published, and has it been updated?

GHSA-6943-qr24-82vx was published on December 2, 2024 and was last updated on December 2, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

sftpgo is a full-featured and highly configurable event-driven file transfer solution. Server protocols: SFTP, HTTP/S, FTP/S, WebDAV. The OpenID Connect implementation allows authenticated users to brute force session cookies and thereby gain access to other users' data, since the cookies are generated predictably using the xid library and are therefore unique but not cryptographically secure. This issue was fixed in version v2.6.4, where cookies are opaque and cryptographically secure strings. All users are advised to upgrade. There are no known workarounds for this vulnerability.

Frequently Asked Questions

### Impact The OpenID Connect implementation, in the affected SFTPGo versions, allows authenticated users to brute force session cookies and thereby gain access to other users' data, since the cookies are generated predictably using the [xid](https://github.com/rs/xid) library and are therefore unique but not cryptographically secure. ### Patches This issue was fixed in version v2.6.4, where cookies are opaque and cryptographically secure strings. ### References https://github.com/drakkan/sftpgo/commit/f30a9a2095bf90c0661b04fe038e3b7efc788bc6
