Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Portal (release.portal.bom) versions from 7.4.0 through before 7.4.3.110 are vulnerable to DNS rebinding attacks, which can let a remote attacker redirect users to arbitrary external URLs. The source does not describe what the attacker needs beyond network access. Upgrade to version 7.4.3.110 or later. Alternatively, change the redirect URL security setting from IP to domain.
