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 self XSS in the tail_ea4_migration.cgi interface (SEC-172).

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

Self XSS (cross-site scripting) vulnerability in cPanel's tail_ea4_migration.cgi interface in versions prior to 60.0.25. Self XSS typically requires the victim to inject the malicious payload themselves, often through social engineering.

MitigationUpgrade cPanel to version 60.0.25 or later to patch the vulnerability.

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 installed cPanel version
    Run the command 'cat /usr/local/cpanel/version' or access WHM and check the cPanel version displayed on the main dashboard
    Affected if The version returned is 59.9999.58 or higher but lower than 60.0.25
  2. Locate the tail_ea4_migration.cgi file
    Check if the file exists at /usr/local/cpanel/base/frontend/paper_lantern/ea4/tail_ea4_migration.cgi or similar paths under /usr/local/cpanel/base/frontend/
    Affected if The file exists and is accessible to authenticated users
  3. Verify the CGI is reachable via web
    Access the URL pattern https://yourserver:2083/cgi/ea4/tail_ea4_migration.cgi or https://yourserver:2087/scripts/tail_ea4_migration.cgi (adjust port based on your setup)
    Affected if The CGI script responds and accepts user input in any parameter field

You are affected if your cPanel version falls within the range 59.9999.58 through 60.0.24 (inclusive) and the tail_ea4_migration.cgi interface is accessible to users who could inject malicious scripts.
