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.
How urgent is this, really
GHSA-cmjc-qp7j-xgwr plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 376,715 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
An authenticated stored Cross-Site Scripting (XSS) vulnerability exists in WSO2 API Manager components (carbon-apimgt) due to insufficient validation of user-supplied input during API document upload in the Publisher portal.
A user with publisher privileges can upload a crafted API document whose contents are later rendered in the UI for other users, leading to attacker-controlled script execution. Likely outcomes include redirection to malicious sites, unauthorized UI modifications, or exfiltration of data accessible to the browser; session hijacking is mitigated by the use of HttpOnly session cookies.
To remediate, update to version 9.31.117 or above.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.wso2.carbon.apimgt:org.wso2.carbon.apimgt.api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.wso2.carbon.apimgt:org.wso2.carbon.apimgt.api to 9.31.117 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cmjc-qp7j-xgwr 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-cmjc-qp7j-xgwr can be triaged on real exposure rather than presence alone.
Tailored to GHSA-cmjc-qp7j-xgwr. 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-cmjc-qp7j-xgwr in your dependencies?
O3 Security finds GHSA-cmjc-qp7j-xgwr across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
