EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Django CMS 3.7.3 does not validate the plugin_type parameter while generating error messages for an invalid plugin type, resulting in a Cross Site Scripting (XSS) vulnerability. The vulnerability allows an attacker to execute arbitrary JavaScript code in the web browser of the affected user.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | django-cms | ≥ 3.7.0&&< 3.7.4 | 3.7.4 |
| 🐍PyPI | django-cms | ≥ 3.6.0&&< 3.6.1 | 3.6.1 |
| 🐍PyPI | django-cms | ≥ 3.5.0&&< 3.5.4 | 3.5.4 |
| 🐍PyPI | django-cms | ≥ 3.4.0&&< 3.4.7 | 3.4.7 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for django-cms. 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.
Fix
Update django-cms to 3.7.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hx7c-qpfq-xcrp is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-hx7c-qpfq-xcrp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-hx7c-qpfq-xcrp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-hx7c-qpfq-xcrp in your dependencies?
O3 detects GHSA-hx7c-qpfq-xcrp across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
