Description
Liferay Portal 7.4.0 through 7.4.3.101, and Liferay DXP 2023.Q3.0 through 2023.Q3.4, 7.4 GA through update 92 and 7.3 GA though update 35 does not limit the number of objects returned from a GraphQL queries, which allows remote attackers to perform denial-of-service (DoS) attacks on the application by executing queries that return a large number of objects.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.portal.vulcan.api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.liferay:com.liferay.portal.vulcan.api to 40.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f3hf-r62c-mfrj is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
