GHSA-cxgv-px37-4mp2 is a high-severity (CVSS 8.6) Server-Side Request Forgery (SSRF) vulnerability in @nuxt/icon. A fix is available for @nuxt/icon — see the affected versions and patch details below.
Nuxt Icon affected by a Server-Side Request Forgery (SSRF)
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-cxgv-px37-4mp2 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,238 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
@nuxt/iconnpmDescription
Summary
nuxt/icon provides an API to allow client side icon lookup. This endpoint is at /api/_nuxt_icon/[name].
The proxied request path is improperly parsed, allowing an attacker to change the scheme and host of the request. This leads to SSRF, and could potentially lead to sensitive data exposure.
Details
The new URL constructor is used to parse the final path. This constructor can be passed a relative scheme or path in order to change the host the request is sent to. This constructor is also very tolerant of poorly formatted URLs.
As a result we can pass a path prefixed with the string http:. This has the effect of changing the scheme to HTTP. We can then subsequently pass a new host, for example http:127.0.0.1:8080. This would allow us to send requests to a local server.
PoC
Make a request to /api/_nuxt_icon/http:example.com, observe the data returned has been fetched from a different resource than intended.
I typically try to find an example within Nuxt infrastructure that is vulnerable to these types of bugs, but I could not identify any with this endpoint enabled.
Impact
- SSRF, potential sensitive data exposure.
- I do not believe this can be chained into an XSS, but it may be possible.
- Does not have a security impact on services deployed on Cloudflare Workers.
- Does not impact certain builds and modes (like static builds).
- Can be mitigated using by disabling the
fallbackToApioption.
Fix
- Ensure the host has not been changed after the path is parsed.
- Alternatively, prefix the path with
./.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @nuxt/icon, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @nuxt/icon to 1.4.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cxgv-px37-4mp2 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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-cxgv-px37-4mp2 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-cxgv-px37-4mp2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-cxgv-px37-4mp2 in your dependencies?
O3 Security finds GHSA-cxgv-px37-4mp2 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
