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 alias upload interface (SEC-184).

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

cPanel before version 60.0.25 contains a self Cross-Site Scripting (XSS) vulnerability in the alias upload interface. An attacker could trick an authenticated user into pasting malicious JavaScript code into the alias upload form, which would then execute in the user's browser session.

MitigationUpgrade cPanel to version 60.0.25 or later. Additionally, implement proper input sanitization and output encoding in the alias upload interface to prevent XSS execution.

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. Identify cPanel version
    Access the cPanel server via command line and run: cat /usr/local/cpanel/version or check the version displayed in the cPanel WHM interface (Home >> Server Information >> cPanel version)
    Affected if The version displayed is 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. Confirm user access to alias upload feature
    Log into cPanel as an authenticated user and navigate to the Domains section (or Aliases) where the alias upload/create interface is located
    Affected if The alias upload interface is accessible and functional in the authenticated session
  3. Verify the XSS payload execution point
    In the alias upload form, locate the input field where domain aliases are entered or uploaded and inspect whether user-supplied input is reflected back without sanitization
    Affected if The alias input field accepts and reflects back raw text/content without visible sanitization or encoding

You are affected if your installed cPanel version falls within any of the affected version ranges (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 have access to the alias upload interface as an authenticated user.
