How severe is CVE-2023-30544?

CVE-2023-30544 has a CVSS score of 3.9/10, rated LOW. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-30544?

CVE-2023-30544 affects the following packages: kiwitcms (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2023-30544?

Update kiwitcms to 12.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-30544 is resolved across your whole dependency graph.

How do I detect CVE-2023-30544 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for kiwitcms. 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-2023-30544 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-2023-30544?

O3 pinpoints whether CVE-2023-30544 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-2023-30544 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-30544 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.

CVE-2023-30544 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 33th 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-2023-30544 published, and has it been updated?

CVE-2023-30544 was published on April 24, 2023 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.
