Which packages are affected by CVE-2019-7725?

CVE-2019-7725 affects the following packages: nukeviet/nukeviet (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2019-7725?

Update nukeviet/nukeviet to 4.3.04 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-7725 is resolved across your whole dependency graph.

How do I detect CVE-2019-7725 in my Packagist dependencies?

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

How do I mitigate CVE-2019-7725 if there is no patch (or I can't update yet)?

Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.

Is CVE-2019-7725 actively exploited in the wild?

No public exploit code has been indexed for CVE-2019-7725 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-2019-7725?

CVE-2019-7725 has an EPSS (Exploit Prediction Scoring System) score of 2.6%, placing it in the 85th 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-2019-7725?
