If you’re digging into software vulnerabilities, there’s a good chance you’ve seen a bunch of CVE identifiers. They help researchers and security teams track and fix security problems. But sometimes, a CVE pops up and then disappears just as quickly. One of those is CVE-2021-46907. If you search for this CVE, you’ll find out that it is REJECTED. What does that mean, and how does a CVE get rejected in the first place?

This article digs deep into CVE-2021-46907—what these rejections mean, why they matter, and how you can spot them in your work. We’ll use simple American language to keep things clear, plus a code example on checking for CVE status yourself.

What is CVE-2021-46907?

When you find CVE-2021-46907 in the CVE database (like here on MITRE), you’ll see this message:

> REJECTED
> "This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. Additional information can be found here: https://cve.mitre.org/"

That’s it—no vulnerability details, no exploit, nothing else.

Out-of-Scope: The issue doesn’t actually fit CVE’s criteria.

- Withdrawn at Request: Perhaps the developer or vendor provided new info or a fix that meant it wasn’t a bug.

If you see a REJECTED CVE like this one, it means the tracking system is keeping things clean and accurate.

What Does a Rejected CVE Look Like?

Here’s what the real MITRE CVE record shows:

Name    CVE-2021-46907

Status  REJECTED

Reason  This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. 
        Further information, including reason for withdrawal, may be available at: 
        https://cve.mitre.org/

What About Exploits or Code?

Since CVE-2021-46907 was never assigned to a real vulnerability, there is no exploit code, proof of concept, or patches available. Nothing to fix—nothing to exploit!

But here’s a sample Python script you can use to check the status of any CVE automatically, so you don’t waste time chasing “ghost” vulnerabilities:

import requests

def check_cve_status(cve_id):
    url = f'https://cveawg.mitre.org/api/cve/{cve_id}';
    response = requests.get(url)
    if response.status_code == 200:
        data = response.json()
        state = data.get("cve", {}).get("CVE_data_meta", {}).get("STATE")
        description = data.get("cve", {}).get("description", {}).get("description_data", [{}])[].get("value")
        print(f"{cve_id} state: {state}")
        print(f"Description: {description}")
    else:
        print(f"{cve_id} not found in database.")

check_cve_status("CVE-2021-46907")
