Cross-site scripting (XSS) vulnerability in the Layout module's SEO configuration in Liferay Portal 7.4.3.70 through 7.4.3.73, and Liferay DXP 7.4 update 70 through 73 allows remote attackers to inject arbitrary web script or HTML via the `_com_liferay_layout_admin_web_portlet_GroupPagesPortlet_backURL` parameter.
Pattern Redirects in Liferay Portal 7.4.3.48 through 7.4.3.76, and Liferay DXP 7.4 update 48 through 76 allows regular expressions that are vulnerable to ReDoS attacks to be used as patterns, which allows remote attackers to consume an excessive amount of server resources via crafted request URLs.
