Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A Stored cross-site scripting vulnerability in the Liferay Portal 7.4.3.120 through 7.4.3.132, and Liferay DXP 2025.Q2.0 through 2025.Q2.8, 2025.Q1.0 through 2025.Q1.15, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13 and 2024.Q1.9 through 2024.Q1.19 allows an remote authenticated attacker to inject JavaScript through the message boards feature available via the web interface.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A stored cross-site scripting (XSS) vulnerability in Liferay Portal and DXP's message boards feature allows an authenticated remote attacker to inject malicious JavaScript that persists and executes when other users view the infected message boards content.

MitigationUpgrade to Liferay 7.4.3.133 or later, or apply the relevant security patch for affected DXP versions; implement input validation and output encoding on message board content as a compensating control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Lifer DXP or Portal version
    Access the Lifer Control Panel, go to Configuration > Server Administration > Product Information, or check the portal-ext.properties file for the version property
    Affected if The installed version falls within any of these ranges: 2024.Q1.9 to 2024.Q1.19; 2024.Q2.1 to 2024.Q2.13; 2024.q3.1 to 2024.q3.13; 2024.q4.0 to 2024.q4.7; 2025.Q1.0 to 2025.Q1.15; 2025.Q2.0 to 2025.Q2.8 (for DXP) or 7.4.3.120 to 7.4.3.132 (for Portal)
  2. Confirm Message Boards module is enabled
    Navigate to Control Panel > Apps > App Manager, or check the OSGi console for the com.lifer.message.boards module bundle status
    Affected if The Message Boards component is active and installed on the system
  3. Verify Message Boards permissions allow user posting
    Go to Control Panel > Users > Roles, check if authenticated users or non-admin roles have Message Boards permission to create or reply to threads
    Affected if Regular authenticated users can post to message boards without admin oversight
  4. Inspect existing Message Boards content for XSS payloads
    Access the Message Boards portlet via the site administration, review recent thread titles and posts for unusual script tags, event handlers, or encoded characters
    Affected if Any message board thread contains unrecognized script tags, javascript: URIs, or HTML event attributes like onload, onerror, or onclick

A system is affected if it runs a Lifer DXP or Portal version within the specified ranges AND has the Message Boards feature enabled with posting permissions for authenticated users.
