Authenticated service interruption via unbounded GraphQL pagination
Published Sep 12, 2025 · Updated Sep 12, 2025
Uncontrolled resource consumption in Liferay Portal and Liferay DXP allows remote authenticated users to interrupt service through GraphQL. The GraphQL pagination path accepts page-size values without enforcing the configured Headless API limit, so queries can return an unbounded number of objects and exhaust application resources. Low-privileged network access to the GraphQL endpoint is required; the reported consequence is application denial of service, with no reported data exposure or modification.
