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
cPanel before 82.0.2 has stored XSS in the WHM Tomcat Manager interface (SEC-504).

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

This is a stored Cross-Site Scripting (XSS) vulnerability in cPanel's WHM (Web Host Manager) Tomcat Manager interface, affecting versions prior to 82.0.2. The vulnerability allows malicious JavaScript to be persisted within the Tomcat Manager, executing when other administrators view the affected interface.

MitigationUpgrade cPanel to version 82.0.2 or later to patch the stored XSS vulnerability in the WHM Tomcat Manager interface.

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. Determine your cPanel version
    Log into WHM and locate the version information, typically found in the left sidebar or via the 'Server Status' > 'Server Information' page. Alternatively, run 'whmapi1 version' from command line.
    Affected if The installed version is lower than 82.0.2
  2. Confirm Tomcat Manager is accessible
    Navigate to WHM > Tomcat Manager interface (usually found under 'Service Configuration' or by searching 'Tomcat' in WHM search bar). Verify the interface loads and is not disabled.
    Affected if Tomcat Manager interface is enabled and accessible in WHM
  3. Inspect Tomcat Manager for suspicious content
    Within the Tomcat Manager interface, review any deployed applications, configuration files, or context parameters for unexpected or malicious-looking script tags, event handlers, or encoded characters that could indicate injected JavaScript.
    Affected if Unexpected script content or potential XSS payloads are present in Tomcat Manager configurations or deployed applications

You are affected if your cPanel version is below 82.0.2 AND the WHM Tomcat Manager interface is enabled and accessible.
