Description

Liferay Portal 7.4.0 through 7.4.3.105, and older unsupported versions, and Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions may incorrectly identify the subdomain of a domain name and create a supercookie, which allows remote attackers who control a website that share the same TLD to read cookies set by the application.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay.portal:com.liferay.portal.impl, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update com.liferay.portal:com.liferay.portal.impl to 96.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-43793 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
