Machine-written summary

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

Liferay Portal 7.3.3 through 7.4.3.97 and Liferay DXP 7.3 before update 34, 7.4 through update 92, and 2023.Q3 before patch 6 have a reflected cross-site scripting flaw on the add assignees to a role page. A remote attacker can inject arbitrary web script or HTML, which can run in a victim's browser if the victim follows a crafted link. Upgrade Liferay Portal to 7.4.3.98 or Liferay DXP to 7.3.10.u34 or 2023.Q3.6.
