Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Portal's Vulcan API (com.liferay.portal.vulcan.api, versions 8.0.2 up to 40.2.0) and Vulcan implementation (com.liferay.portal.vulcan.impl, versions 5.0.7 up to 5.0.105) do not limit the number of objects returned by GraphQL queries. A remote attacker can run queries that return very large numbers of objects, causing denial of service. Upgrade com.liferay.portal.vulcan.api to 40.2.0 and com.liferay.portal.vulcan.impl to 5.0.105.
