Description
In Liferay Portal before 7.3.2 and Liferay DXP 7.0 before fix pack 92, 7.1 before fix pack 18, and 7.2 before fix pack 6, the template API does not restrict user access to sensitive objects, which allows remote authenticated users to execute arbitrary code via crafted FreeMarker and Velocity templates.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay.portal:release.portal.bom, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.liferay.portal:release.portal.bom to 7.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-13445 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
