How severe is GHSA-cpg4-qcj8-42gp?

No CVSS score has been assigned to GHSA-cpg4-qcj8-42gp yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-cpg4-qcj8-42gp?

GHSA-cpg4-qcj8-42gp affects the following packages: com.liferay:com.liferay.portal.workflow.kaleo.forms.web (Maven). Ecosystems affected: Maven.

How do I fix GHSA-cpg4-qcj8-42gp?

Update com.liferay:com.liferay.portal.workflow.kaleo.forms.web to 5.0.107 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cpg4-qcj8-42gp is resolved across your whole dependency graph.

How do I detect GHSA-cpg4-qcj8-42gp in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.portal.workflow.kaleo.forms.web, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-cpg4-qcj8-42gp if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-cpg4-qcj8-42gp actively exploited in the wild?

No public exploit code has been indexed for GHSA-cpg4-qcj8-42gp 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 GHSA-cpg4-qcj8-42gp?

GHSA-cpg4-qcj8-42gp has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 13th 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.
