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 62.0.4 allows self XSS on the paper_lantern password-change screen (SEC-197).

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 · moderate confidence

cPanel versions before 62.0.4 contain a self Cross-Site Scripting (XSS) vulnerability in the paper_lantern theme's password-change screen (SEC-197). The vulnerability allows malicious JavaScript to be injected and executed in the context of the user's browser when changing their password.

MitigationUpgrade cPanel to version 62.0.4 or later to patch the self XSS vulnerability in the paper_lantern password-change 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 installed cPanel version
    Run the command: /usr/local/cpanel/cpanel -V or check /usr/local/cpanel/version
    Affected if The version falls within any of these ranges: 11.54.0.0-11.54.0.35, 55.9999.61-56.0.42, 57.9999.48-58.0.42, 59.9999.58-60.0.34, or 61.9999.55-62.0.3

    Check /var/cpanel/users/username or WHM interface for the active cPanel theme setting
    Affected if The paper_lantern theme is the active theme for the cPanel account
  3. Confirm password change interface is accessible
    Navigate to cPanel > Password Change or access /password/ endpoint
    Affected if The password change interface is accessible to end users on the affected version

A user is affected if their cPanel version falls within any of the listed vulnerable ranges and the paper_lantern theme is in use with the password change functionality accessible.
