Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Liferay Portal's com.liferay.portal.workflow.kaleo.designer.web package, versions before 5.0.145, is vulnerable to a regular expression denial of service in the Role Name search field of the Kaleo Designer portlet. An authenticated user with permission to update Kaleo Workflows can enter a crafted regex pattern that makes their own browser hang for a long time. Upgrade to version 5.0.145.
