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 82.0.15 allows self XSS in the SSL Certificate Upload interface (SEC-521).

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 before version 82.0.15 contains a self Cross-Site Scripting (XSS) vulnerability in the SSL Certificate Upload interface. An attacker could inject malicious JavaScript that executes within the context of the user's session when they upload or interact with SSL certificates.

MitigationUpdate cPanel to version 82.0.15 or later. As a self XSS, this requires user interaction to exploit; avoid pasting untrusted code into browser developer tools or the 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. Verify cPanel is installed
    Check for cPanel installation by looking for /usr/local/cpanel directory or run: ls -la /usr/local/cpanel
    Affected if cPanel directory does not exist means not affected
  2. Determine installed cPanel version
    Run: /usr/local/cpanel/cpanel -V or check /usr/local/cpanel/version file
    Affected if Cannot determine version means not affected
  3. Compare version against affected ranges
    Review the version output against: 77.9999.110 to 78.0.38, or 81.9999.242 to 82.0.14
    Affected if Installed version falls within either range indicates affected
  4. Confirm SSL Certificate Upload interface is accessible
    Log into cPanel as a user and navigate to SSL/TLS section under Security, or check via WHM List Accounts and access cPanel for any account
    Affected if Interface is accessible and version is in affected range indicates vulnerable to exploitation

User is affected if cPanel is installed, the installed version falls within 77.9999.110-78.0.38 or 81.9999.242-82.0.14, and the SSL Certificate Upload interface is accessible to users.
