CVE-2025-43752Network attack vector

Service interruption via orphaned attachment uploads

Published Aug 22, 2025 · Updated Aug 22, 2025

Resource exhaustion in affected Liferay Portal and DXP releases allows remote authenticated users to interrupt service through file uploads. Object-entry attachment fields create document-library file entries but fail to delete them when an entry is abandoned, a file is replaced, or the page is refreshed. Access to attachment-enabled object-entry forms is required, and repeated uploads can consume storage until the service becomes unavailable.
