CVE-2025-62260Network attack vector

Authenticated service interruption via unbounded API pagination

Published Oct 27, 2025 · Updated Oct 27, 2025

Uncontrolled resource consumption in Liferay Portal and DXP allows remote authenticated users to interrupt service through Headless API requests. The Headless API pagination context accepts a requested page size without enforcing an upper bound, so one response can materialize an excessive number of objects. A low-privileged account and network access are required; the resulting resource exhaustion affects availability without reported data disclosure or modification.
