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 82.0.2 has Self XSS in the cPanel and webmail master templates (SEC-506).

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

This is a Self XSS (Cross-Site Scripting) vulnerability in cPanel versions before 82.0.2. The vulnerability exists in the cPanel and webmail master templates, allowing an attacker to inject malicious scripts that would be reflected back to the user. Self XSS requires the victim to manually paste the malicious script into input fields, making it less exploitable than stored XSS but still a valid security risk.

MitigationUpdate cPanel to version 82.0.2 or later to remediate this vulnerability. This is a vendor-provided patch update.

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. Retrieve the installed cPanel version
    Run the command `whmapi1 get_version` or check the file `/usr/local/cpanel/version` to obtain the currently installed cPanel version number.
    Affected if The version returned is below 82.0.2 (for example, 82.0.1, 81.x, or earlier).
  2. Verify the version against the affected range
    Compare the retrieved version number to the vulnerable threshold of 82.0.2. Any version string that is lexicographically or numerically lower than 82.0.2 is in the affected range.
    Affected if The installed version is less than 82.0.2.
  3. Confirm cPanel or webmail interfaces are in use
    Check if cPanel or webmail interfaces are accessible or configured in the environment. This can be confirmed by accessing the cPanel login page at port 2082 (cPanel) or 2096 (webmail) or by checking for cPanel service processes running.
    Affected if cPanel or webmail interfaces are active and the version is below 82.0.2.

The environment is affected if the installed cPanel version is lower than 82.0.2 and cPanel or webmail interfaces are in use, since the vulnerable master templates are present by default in those versions.
