CVE-2025-43801Network attack vector

Service interruption via crafted XML-RPC request

Published Sep 16, 2025 · Updated Sep 16, 2025

Unchecked loop input in Liferay Portal and DXP XML-RPC allows remote attackers to interrupt service with crafted requests. Liferay identifies XML-RPC as the affected component but has not disclosed the loop, attacker-controlled field, or resource-exhaustion path. No authentication or user interaction is required, and the published impact is limited to service availability without a stated crash, hang, or recovery mode.
