Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Portal (release.portal.bom 7.4.0 through 7.4.3.107, and com.liferay.portal.impl before 96.0.0) is vulnerable to path traversal and denial-of-service in its ComboServlet. A remote attacker can use crafted query strings in a URL to read arbitrary CSS and JS files and load files repeatedly. Upgrade release.portal.bom to 7.4.3.108-ga108 or com.liferay.portal.impl to 96.0.0.
