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 80.0.5 allows local code execution in the context of a different cPanel account because of insecure cpphp execution (SEC-486).

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 80.0.5 contains an insecure cpphp (cPanel PHP wrapper) execution vulnerability that allows local privilege escalation. An attacker with access to one cPanel account can execute arbitrary code in the context of a different cPanel user account, effectively bypassing account isolation.

MitigationUpgrade cPanel to version 80.0.5 or later to remediate the insecure cpphp execution. This is a local privilege escalation requiring prior authenticated access to the system.

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. Confirm cPanel installation
    Run 'ls -la /usr/local/cpanel' or check if the /usr/local/cpanel directory exists on the system
    Affected if The /usr/local/cpanel directory does not exist, meaning cPanel is not installed and this CVE does not apply
  2. Identify installed cPanel version
    Execute '/usr/local/cpanel/cpanel -V' or 'cat /usr/local/cpanel/version' to retrieve the installed cPanel version number
    Affected if The command fails or returns no version, indicating cPanel is not properly installed
  3. Compare version against affected range
    Compare the retrieved version number to 80.0.5 - versions before 80.0.5 are affected (for example, 78.x, 79.x)
    Affected if The installed version is numerically less than 80.0.5 (for example, 78.0.0, 79.0.12, or any 80.0.x version before 80.0.5)
  4. Verify cpphp binary presence
    Check if /usr/local/cpanel/bin/cpphp exists using 'ls -la /usr/local/cpanel/bin/cpphp'
    Affected if The cpphp binary exists and the cPanel version is below 80.0.5 - this indicates the vulnerable configuration is present

If cPanel is installed and the version is below 80.0.5, the environment is affected by this local privilege escalation vulnerability in the cpphp wrapper.
