Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Site Admin Web (com.liferay.site.admin.web) versions before 5.0.111 are affected. In Liferay Portal and DXP, newly created sites default to an "Open" membership type, so any registered user can join. A remote attacker with a registered account can then view, add, or edit content on the site. Upgrade com.liferay.site.admin.web to version 5.0.111 or later.
