How severe is GHSA-2xgm-wc4g-5jvg?

No CVSS score has been assigned to GHSA-2xgm-wc4g-5jvg yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-2xgm-wc4g-5jvg?

GHSA-2xgm-wc4g-5jvg affects the following packages: n8n (npm). Ecosystems affected: npm.

How do I fix GHSA-2xgm-wc4g-5jvg?

Update n8n to 2.28.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2xgm-wc4g-5jvg is resolved across your whole dependency graph.

How do I detect GHSA-2xgm-wc4g-5jvg in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for n8n, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-2xgm-wc4g-5jvg 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-2xgm-wc4g-5jvg actively exploited in the wild?

No public exploit code has been indexed for GHSA-2xgm-wc4g-5jvg 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-2xgm-wc4g-5jvg?

GHSA-2xgm-wc4g-5jvg has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 19th 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-2xgm-wc4g-5jvg?

GHSA-2xgm-wc4g-5jvg is classified as CWE-639 (CWE-639). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-2xgm-wc4g-5jvg published, and has it been updated?

GHSA-2xgm-wc4g-5jvg was published on July 22, 2026 and was last updated on July 22, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

An authenticated user with permission to create workflows in one project could bypass project/folder authorization boundaries during workflow creation. By supplying a crafted request payload, the user could associate a newly created workflow with a folder belonging to a different project they do not have access to.

The workflow itself remains in the attacker's project and is not visible to the target project's members. The target project's folder ownership is not changed, and no data from the target project is exposed. The impact is limited to a logical integrity violation of the target project's folder structure at the database level.

This issue affects instances with multi-project and folder support enabled.

Patches

The issue has been fixed in n8n version 2.28.0. Users should upgrade to this version or later to remediate the vulnerability.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

Restrict project membership and workflow creation permissions to fully trusted users only.

This workaround does not fully remediate the risk and should only be used as a short-term mitigation measure.
