How severe is CVE-2022-30184?

CVE-2022-30184 has a CVSS score of 5.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2022-30184?

CVE-2022-30184 affects the following packages: NuGet.Commands (NuGet), NuGet.CommandLine (NuGet), NuGet.CommandLine.XPlat (NuGet), NuGet.Commands (NuGet), NuGet.Commands (NuGet), NuGet.Commands (NuGet), NuGet.Commands (NuGet), NuGet.Commands (NuGet), and 13 more. Ecosystems affected: NuGet.

How do I fix CVE-2022-30184?

Update NuGet.Commands to 4.9.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-30184 is resolved across your whole dependency graph.

How do I detect CVE-2022-30184 in my NuGet dependencies?

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

How do I mitigate CVE-2022-30184 if there is no patch (or I can't update yet)?

Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.

Is CVE-2022-30184 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-30184 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 CVE-2022-30184?

CVE-2022-30184 has an EPSS (Exploit Prediction Scoring System) score of 6.1%, placing it in the 93th 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 CVE-2022-30184?

CVE-2022-30184 is classified as Information Exposure (CWE-200). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2022-30184 published, and has it been updated?

CVE-2022-30184 was published on June 15, 2022 and was last updated on October 24, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
