CVE-2025-46377 - The Rejected Vulnerability – Understanding Why "Not Used" Is Sometimes the Best Response

When new Common Vulnerabilities and Exposures (CVEs) get assigned, not all stick around or result in a scramble for patching. Some, like CVE-2025-46377, end up with a simple, clear (and maybe a bit mysterious) status: "Rejected", followed by the reason "Not used".

In this article, we’ll break down what this means, what happens when a CVE gets rejected, and why this particular CVE won’t keep anyone up at night.

What Is CVE-2025-46377?

First, some basics: A CVE identifier is issued anytime someone reports a security flaw in software or hardware. This lets the community track, discuss, and eventually fix it. Each CVE has a record with details on the affected software, description, and possible mitigating steps.

But sometimes, a CVE doesn’t describe a real bug. Maybe it was reported in error, it describes behavior that's not a vulnerability, or the entry gets created by accident. That’s where the "REJECT" status comes in.

The Official Entry

You can find CVE-2025-46377 here:
NVD CVE Entry:
https://nvd.nist.gov/vuln/detail/CVE-2025-46377


Here’s what it says

> REJECT
> This candidate has been rejected by its producer.
> Reason: Not used.

You might also find it listed in the MITRE CVE database with the same note.

What Does "Not Used" Mean?

In simple language: No actual vulnerability, no need to do anything.

Clerical Error: The entry was opened in error.

"Not used" typically means either the slot was created but never needed, or something in the reporting process revealed no real vulnerability existed. This is good news!

No Code, No Exploit, No Patch

Since CVE-2025-46377 is not a “real” vulnerability, there’s no code showing a bug and no way to write an exploit. You won’t find any "proof of concept," and developers don’t need to ship a patch. If you’re scanning your environment for this CVE, you can safely ignore any alerts—it’s as if this ID never existed.

Here’s a hypothetical "exploit" to illustrate its emptiness

# Fake Exploit for CVE-2025-46377
def exploit():
    print("Nothing to do! This vulnerability was never used.")

if __name__ == "__main__":
    exploit()

When you run it

Nothing to do! This vulnerability was never used.

Why Document Rejected CVEs?

You might wonder why rejected CVEs stick around instead of being erased. It’s all about transparency and tracking. By officially marking them as rejected, the community avoids confusion if someone finds the ID later, and researchers don't waste time chasing phantoms.

It also allows vulnerability scanners, security teams, and software inventories to mark them as "not an issue," giving peace of mind.

In Summary

CVE-2025-46377 is a reminder that not every reported security issue turns out to be a real risk. The "Not used" status is a straightforward way of saying: “There’s nothing here to worry about.”

If you ever run into this CVE on a report or in a vulnerability scan—move along, there’s truly nothing to see.
