Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.portal.workflow.kaleo.designer.web, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.liferay:com.liferay.portal.workflow.kaleo.designer.web to 5.0.124 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xcvw-hh99-qm73 is resolved across your whole dependency graph.
Workarounds
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.
