CVE-2025-62264
📋 TL;DR
This reflected cross-site scripting (XSS) vulnerability in Liferay Portal and DXP allows remote attackers to inject malicious scripts or HTML via a specific parameter. Attackers can steal session cookies, redirect users to malicious sites, or perform actions on behalf of authenticated users. Organizations running affected Liferay versions with internet-facing portals are at risk.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator session cookies, gain full administrative access to the portal, and potentially compromise the entire Liferay instance and connected systems.
Likely Case
Attackers steal user session cookies, impersonate legitimate users to access sensitive data, or redirect users to phishing sites to harvest credentials.
If Mitigated
With proper input validation and output encoding, the malicious payload is neutralized before execution, preventing any impact.
🎯 Exploit Status
Exploitation requires tricking a user into clicking a malicious link containing the crafted parameter; no authentication is needed.

🔧 Temporary Workarounds
Input Validation Filter
allImplement a web application firewall (WAF) or custom filter to block requests containing malicious script patterns in the _com_liferay_portal_language_override_web_internal_portlet_PLOPortlet_selectedLanguageId parameter.
🧯 If You Can't Patch
- Implement a WAF with XSS protection rules to block malicious payloads.
- Disable or restrict access to the Language Override portlet if not required.
🔍 How to Verify
Check if Vulnerable:
Test by sending a request with a script payload in the _com_liferay_portal_language_override_web_internal_portlet_PLOPortlet_selectedLanguageId parameter and checking if it executes in the response.Check Version:
Check the Liferay version via the Control Panel or by examining the liferay-portal.jar file version.Verify Fix Applied:
After patching, repeat the test; the script should be properly encoded and not execute.📡 Detection & Monitoring
Log Indicators:
- Log entries showing requests with suspicious script patterns in the selectedLanguageId parameter.
- Unexpected error logs from the Language Override portlet.
Network Indicators:
- HTTP requests containing script tags or JavaScript in the selectedLanguageId parameter.
