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 68.0.15 allows unprivileged users to access restricted directories during account restores (SEC-311).

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 68.0.15 contains a privilege escalation vulnerability where unprivileged users can access restricted directories during the account restoration process, bypassing intended access controls.

MitigationUpdate cPanel to version 68.0.15 or later to patch the vulnerability. Verify that account restore functionality still works correctly after the 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. Check installed cPanel version
    Run the command to display the cPanel version, typically via /usr/local/cpanel/cpanel -V or checking the RPM package version on the system
    Affected if The installed version falls within any of these ranges: 61.9999.55 to 62.0.34, 63.9999.74 to 64.0.41, 65.9999.38 to 66.0.33, or 67.9999.64 to 68.0.14
  2. Identify unprivileged user accounts
    Review system accounts to determine if non-administrative users exist who might access the account restoration feature
    Affected if Non-privileged user accounts exist on a system running a vulnerable cPanel version
  3. Verify account restore access controls
    Examine whether the account restoration functionality can be invoked by unprivileged users through WHM API or interface without proper privilege escalation
    Affected if Unprivileged users can trigger account restoration and bypass intended directory access restrictions

A system is affected if the cPanel version is within any of the four vulnerable ranges AND unprivileged users can access the account restoration feature, allowing them to reach restricted directories.
