How severe is CVE-2013-7048?

No CVSS score has been assigned to CVE-2013-7048 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2013-7048?

CVE-2013-7048 affects the following packages: nova (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2013-7048?

Update nova to 12.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-7048 is resolved across your whole dependency graph.

How do I detect CVE-2013-7048 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nova. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2013-7048 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2013-7048?

O3 pinpoints whether CVE-2013-7048 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2013-7048 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2013-7048, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2013-7048?

CVE-2013-7048 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 37th 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.

When was CVE-2013-7048 published, and has it been updated?

CVE-2013-7048 was published on January 23, 2014 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
