How severe is GHSA-9hrv-gvrv-6gf2?

No CVSS score has been assigned to GHSA-9hrv-gvrv-6gf2 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-9hrv-gvrv-6gf2?

GHSA-9hrv-gvrv-6gf2 affects the following packages: flowise (npm), flowise-components (npm). Ecosystems affected: npm.

How do I fix GHSA-9hrv-gvrv-6gf2?

Update flowise to 3.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9hrv-gvrv-6gf2 is resolved across your whole dependency graph.

How do I detect GHSA-9hrv-gvrv-6gf2 in my npm dependencies?

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

How do I mitigate GHSA-9hrv-gvrv-6gf2 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.

How does O3 Security protect against GHSA-9hrv-gvrv-6gf2?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-9hrv-gvrv-6gf2 can be triaged on real exposure rather than presence alone.

Is GHSA-9hrv-gvrv-6gf2 actively exploited in the wild?

No public exploit code has been indexed for GHSA-9hrv-gvrv-6gf2 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-9hrv-gvrv-6gf2?

GHSA-9hrv-gvrv-6gf2 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 25th 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-9hrv-gvrv-6gf2?

GHSA-9hrv-gvrv-6gf2 is classified as Server-Side Request Forgery (SSRF) (CWE-918). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-9hrv-gvrv-6gf2 published, and has it been updated?

GHSA-9hrv-gvrv-6gf2 was published on April 16, 2026 and was last updated on July 8, 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

Summary

The attacker provides an intranet address through the base url field configured in the Execute Flow node → Bypass checkDenyList / resolveAndValidate in httpSecurity.ts (not called) → Causes the server to initiate an HTTP request to any internal network address, read cloud metadata, or detect internal network services

Details

Then initiate the call:

POST /api/v1/prediction/d6739838-d3b3-43d9-86ff-911a3d757a7e HTTP/1.1
Host: 127.0.0.1:3000
Content-Type: application/json

Impact

This is a Server-Side Request Forgery (SSRF) vulnerability that may lead to the following risks:

Explore Internal Web Applications
Access sensitive management interfaces
Leak internal configuration, credentials, or confidential information

This vulnerability significantly increases the risk of internal service enumeration and potential lateral movement in enterprise environments.

Detection & mitigation playbook

Open-source dependency

Detect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for flowise, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update flowise to 3.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9hrv-gvrv-6gf2 is resolved across your whole dependency graph.
Workarounds
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.
