CVE-2025-43806
📋 TL;DR
This vulnerability allows remote authenticated users to bypass permission checks in Liferay's Batch Engine, enabling unauthorized access to exported data via REST APIs. It affects Liferay Portal 7.4.0-7.4.3.112 and Liferay DXP 2023.Q4.0-2023.Q4.7, 2023.Q3.1-2023.Q3.10, and 7.4 GA through update 92.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Authenticated attackers could exfiltrate sensitive data from the system, potentially including user information, configuration data, or business-critical information.
Likely Case
Privilege escalation where authenticated users with limited permissions can access data they shouldn't be able to view, leading to data exposure.
If Mitigated
Minimal impact if proper network segmentation, API access controls, and monitoring are in place to detect unauthorized data export attempts.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of REST API endpoints. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Liferay Portal 7.4.3.113 or later; Liferay DXP 2023.Q4.8 or later, 2023.Q3.11 or later, or 7.4 update 93 or later

🔧 Temporary Workarounds
Restrict REST API Access
allImplement network-level restrictions to limit access to Liferay REST APIs to only trusted sources.
Enhanced Authentication Controls
allImplement multi-factor authentication and strict access controls to reduce risk of unauthorized authenticated access.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Liferay instances from sensitive data stores
- Deploy web application firewall rules to monitor and block suspicious batch export API calls
🔍 How to Verify
Check if Vulnerable:
Check Liferay version via Control Panel > Configuration > Server Administration > System InformationCheck Version:
Check via Liferay Control Panel or examine liferay-portal.xml version informationVerify Fix Applied:
Verify version is updated to patched version and test batch export permissions with different user roles📡 Detection & Monitoring
Log Indicators:
- Unusual batch export activity from non-admin users
- Multiple failed permission checks on export tasks
- High volume of data export requests
Network Indicators:
- Unusual REST API calls to batch engine endpoints
- Large data transfers from Liferay instances
