How severe is CVE-2025-24370?

No CVSS score has been assigned to CVE-2025-24370 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-24370?

CVE-2025-24370 affects the following packages: django-unicorn (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2025-24370?

Update django-unicorn to 0.62.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-24370 is resolved across your whole dependency graph.

How do I detect CVE-2025-24370 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for django-unicorn. 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-2025-24370 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-2025-24370?

O3 pinpoints whether CVE-2025-24370 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-2025-24370 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-24370 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-2025-24370?

CVE-2025-24370 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 36th 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-2025-24370 published, and has it been updated?

CVE-2025-24370 was published on February 3, 2025 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.

Description

Django-Unicorn adds modern reactive component functionality to Django templates. Affected versions of Django-Unicorn are vulnerable to python class pollution vulnerability. The vulnerability arises from the core functionality set_property_value, which can be remotely triggered by users by crafting appropriate component requests and feeding in values of second and third parameter to the vulnerable function, leading to arbitrary changes to the python runtime status. With this finding at least five ways of vulnerability exploitation have been observed, stably resulting in Cross-Site Scripting (XSS), Denial of Service (DoS), and Authentication Bypass attacks in almost every Django-Unicorn-based application. This issue has been addressed in version 0.62.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
