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 60.0.25 allows stored XSS during the homedir removal phase of WHM Account termination (SEC-174).

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

Stored XSS vulnerability in cPanel's WHM interface (versions before 60.0.25) that allows injection of malicious scripts during the homedir removal phase when terminating a customer account. The injected payload is stored and executes when administrators interact with termination logs or related interfaces.

MitigationUpgrade cPanel to version 60.0.25 or later to remediate the stored XSS vulnerability in the account termination workflow.

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/WHM version
    Log into WHM and navigate to Server Information > Server Status, or run the command: /usr/local/cpanel/cpanel -V
    Affected if The displayed version falls within any of these ranges: 11.54.0.0 to 11.54.0.32, 55.9999.61 to 56.0.38, 57.9999.48 to 58.0.36, or 59.9999.58 to 60.0.24
  2. Verify WHM account termination feature is accessible
    Confirm you have root access to WHM and the 'Terminate Accounts' or 'Delete Account' function is available in WHM under Account Functions
    Affected if You can access the account termination interface in WHM on an affected version
  3. Check for any terminated accounts in logs
    In WHM, navigate to Account Information > List Terminated Accounts (or view termination logs via the command line in /var/log/)
    Affected if There are terminated accounts present and your WHM version is in the affected range, the stored XSS payload could execute when viewing these logs

You are affected if your cPanel/WHM version is 11.54.0.0-11.54.0.32, 55.9999.61-56.0.38, 57.9999.48-58.0.36, or 59.9999.58-60.0.24 AND you use the WHM account termination feature.
