How to Check cPanel/WHM Version: 6 Methods for SSH, Command Line, WHM Dashboard, and cPanel Interface (Updated 2026)

---

Why Checking Your cPanel/WHM Version Matters More Than Ever

Knowing your exact cPanel and WHM version number is no longer just a housekeeping task — in 2026, it is a critical security responsibility. cPanel is the control panel software running on servers that collectively manage over 70 million domains worldwide, making it one of the most targeted platforms in the web hosting industry. In just the first five months of 2026, multiple emergency Technical Security Releases (TSRs) were issued for critical vulnerabilities, including an authentication bypass (CVE-2026-41940) actively exploited as a zero-day before a patch was even available, followed by three high-severity CVEs patched in May 2026 affecting every supported version from 11.86 through 11.136.

In this environment, being able to instantly verify your cPanel/WHM version is the first step in every security checklist. If you don’t know what version you’re running, you cannot determine whether your server is patched, vulnerable, or eligible for an update.

Beyond security, your cPanel/WHM version matters for:

• Compatibility — Confirming that third-party plugins, WHMCS billing integrations, CloudLinux features, Imunify360, and custom scripts are compatible with your installed version
• Support tickets — Every cPanel support engineer and hosting provider support team will ask for your version number as the first diagnostic step
• Update planning — Understanding which release tier (RELEASE, CURRENT, EDGE, STABLE, LTS) your server is on and whether it’s receiving updates
• Audit and compliance — Documenting server software versions for internal audits, security assessments, or client reporting
• Troubleshooting — Narrowing down whether a bug or behavioral change was introduced in a specific build

This guide covers every method available to check your cPanel and WHM version — from quick SSH one-liners to the WHM dashboard, from the cPanel user interface to API queries — so you can use whichever approach fits your situation.

The Fastest Ways to Check cPanel/WHM Version

If you’re in a hurry, here are the two fastest methods:

Via SSH (root access):

/usr/local/cpanel/cpanel -V

Via WHM Dashboard (no SSH needed): Log into WHM → The version appears in the top-right corner of every page.

Understanding cPanel/WHM Version Numbers

Before checking your version, it helps to understand what the version string actually means. A typical cPanel/WHM version number looks like:

11.136.0.9

Breaking this down:

Segment	Value	Meaning
Major version	11	The major cPanel product generation (has been 11 for many years)
Minor version	136	The feature release number — this is what most people refer to as “the version”
Patch level	0	The patch series within the minor version
Build number	9	The specific build within the patch series

So when someone says “cPanel version 136,” they mean minor version 136. As of May 2026, version 136 is the current RELEASE tier, with version 138 available on the EDGE tier for testing.

cPanel Release Tiers

cPanel uses a tiered release system. Servers are assigned to one of these update tiers:

Tier	Description	Recommended For
RELEASE	Stable, production-tested builds	Most production servers
CURRENT	Newer features, still well-tested	Tech-forward hosting providers
EDGE	Bleeding-edge, may contain bugs	Development/staging servers only
STABLE	Older long-term stable builds	Conservative environments
LTS	Long-term support, security patches only	Legacy server maintenance

To check which tier your server is on:

cat /etc/cpupdate.conf | grep CPANEL

---

Method 1: Check cPanel/WHM Version via the cpanel -V Command (SSH)

This is the most direct, universally reliable method — one command, one output, done.

Prerequisites

• SSH access to the server
• Root user privileges (or a sudo-capable user)

Step-by-Step

Step 1: Connect to your server via SSH:

ssh root@your-server-ip

Step 2: Run the version command:

/usr/local/cpanel/cpanel -V

Step 3: Read the output. You will see something like:

11.136.0.9 (build 9)

Or in newer builds, the output may be formatted as:

11.136.0.9

What the Output Means

• 11.136.0.9 — Full version string (Major.Minor.Patch.Build)
• build 9 — The specific build number within this release

Why This Method Is Preferred

• Works on every cPanel/WHM server regardless of version, configuration, or control panel access
• Executes in under one second
• No file editing or navigation required
• Can be incorporated into scripts and automation (e.g., Ansible playbooks, monitoring scripts)
• Always reflects the currently installed and active version

---

Method 2: Check cPanel Version via the Version File (SSH)

cPanel stores its version in a plain-text file on disk. Reading this file is another quick, scriptable approach.

Step-by-Step

Step 1: Log in via SSH as root.

Step 2: Display the version file:

cat /usr/local/cpanel/version

Step 3: View the output:

11.136.0.9

Difference from Method 1

The version file contains only the version string with no label or wrapper. This makes it ideal for:

• Shell scripting — Easy to capture the output directly into a variable:

  CPANEL_VERSION=$(cat /usr/local/cpanel/version)echo "Server is running cPanel $CPANEL_VERSION"
  

• Monitoring systems — Tools like Nagios, Zabbix, or custom monitoring scripts can read this file directly
• Automated compliance checks — Compare against a minimum required version to flag outdated servers

Alternative Version File Path

On some server configurations, the version is also accessible via:

cat /var/cpanel/version

This file may contain additional metadata depending on the installation. If both files exist, /usr/local/cpanel/version is always authoritative.

---

Method 3: Check cPanel/WHM Version Using the whmapi1 Command (SSH)

For server administrators who use cPanel’s API infrastructure, the whmapi1 command-line tool provides structured version information useful in automation and scripting workflows.

Step-by-Step

Step 1: Log in via SSH as root.

Step 2: Run the API version query:

whmapi1 version

Step 3: Read the structured output:

---
data:
  version: 11.136.0.9
metadata:
  command: version
  reason: OK
  result: 1
  version: 1

Why Use This Method?

• Returns structured YAML output that can be parsed by configuration management tools
• Confirms the API service itself is responding (useful for diagnosing cPanel API issues)
• Can be extended to pull additional server metadata alongside version info
• Useful in Ansible, Puppet, or Chef roles that manage cPanel servers

JSON Output Format (for API integrations)

whmapi1 --output=json version

Returns:

{
  "data": {
    "version": "11.136.0.9"
  },
  "metadata": {
    "command": "version",
    "reason": "OK",
    "result": 1,
    "version": 1
  }
}

Method 4: Check cPanel/WHM Version via the /scripts/upcp Update Script (SSH)

This method not only shows your current version but also tells you what version you would update to if you ran a full update — making it a dual-purpose diagnostic tool.

Step-by-Step (Dry Run — Does Not Update)

Step 1: Log in via SSH as root.

Step 2: Check the update status (read-only, no changes applied):

/scripts/upcp --check

Step 3: Review the output, which includes:

• Current installed version
• Available version on your release tier
• Whether an update is pending
• Update tier configuration

Example output:

Current cPanel & WHM Version: 11.136.0.9
Available Version: 11.136.0.12
An update is available. Run /scripts/upcp to update.

Important: Running /scripts/upcp without --check will initiate a live cPanel update. Always use --check if you only want to view version information without making changes.

When to Use This Method

• To immediately see if your server is running the latest patch within its tier
• After a reported vulnerability (like the May 2026 CVEs) to confirm whether your build is patched
• As part of a pre-maintenance checklist before making server configuration changes

Method 5: Check cPanel/WHM Version via the WHM Dashboard (No SSH Required)

For server administrators and resellers who prefer a graphical interface — or who don’t have SSH access — WHM displays the version prominently without any navigation required.

Step-by-Step

Step 1: Open your browser and navigate to WHM:

https://your-server-ip:2087

or

https://yourhostname.com:2087

Step 2: Log in with your root or reseller credentials.

Step 3: Once logged in, locate the version information. Depending on your WHM theme (Jupiter or Paper Lantern):

Jupiter Theme (current default):

• The cPanel/WHM version number is displayed in the left sidebar, near the bottom, below the navigation menu
• It is also visible in WHM → Server Information (search “Server Information” in the WHM search bar)

Paper Lantern Theme (legacy):

• The version is displayed in the top-right corner of the WHM interface on every page
• Format: cPanel & WHM 11.136 (build 9)

Step 4: Note the full version string shown, including the build number.

Finding Version via WHM Search

If you cannot immediately locate the version display:

1. In WHM, use the search bar at the top of the left navigation panel
2. Type “Server Information” and click the result
3. The Server Information page lists:
   • cPanel & WHM version
   • Operating system and kernel version
   • Server hostname
   • CloudLinux version (if applicable)
   • Apache/Nginx version
   • PHP version(s)
   • MySQL/MariaDB version

This page is useful when you need to collect full server environment details for a support ticket.

Method 6: Check cPanel Version from the cPanel User Interface (No Root Access Required)

If you are a shared hosting customer (not a server administrator) or a cPanel account holder without WHM access, you can still find the cPanel version from within your own cPanel dashboard.

Step-by-Step

Step 1: Log into your cPanel account:

https://yourdomain.com:2083

or via your hosting provider’s login portal.

Step 2: Scroll to the very bottom of the cPanel home page (any theme).

Step 3: In the footer, you will see a line similar to:

cPanel 11.136.0 (build 9)

The version is displayed in small text in the footer of every cPanel page.

Alternative: cPanel Statistics Sidebar

In some cPanel themes, the version is also visible in the Statistics panel on the right-hand side of the cPanel home screen, along with disk usage, bandwidth, and other account metrics.

Why This Method Matters

Many shared hosting customers need their cPanel version to:

• Verify compatibility before installing a plugin or script
• Report their environment to a WordPress plugin or theme developer
• Confirm with their hosting provider that the server is running a supported version
• Check whether they are on a version affected by a known vulnerability

---

Bonus: Check cPanel Version Programmatically via the HTTP API

For developers building integrations or hosting management dashboards, cPanel’s HTTP API exposes the version without requiring SSH:

Using cURL (WHM API Token)

First, generate an API token in WHM under WHM → Development → Manage API Tokens. Then:

curl -sk -H "Authorization: whm root:YOUR_API_TOKEN" \
  "https://your-server:2087/json-api/version"

Response:

{
  "data": {
    "version": "11.136.0.9"
  },
  "metadata": {
    "command": "version",
    "reason": "OK",
    "result": 1,
    "version": 1
  }
}

This approach is ideal for:

• WHMCS plugins and billing system integrations
• Custom server monitoring dashboards
• Automated compliance reporting systems
• Multi-server management consoles

How to Check If Your cPanel/WHM Is Up to Date

Knowing your version is only half the picture — you also need to know whether it is the latest available version for your release tier. Here’s how:

Method 1: The --check Flag

/scripts/upcp --check

This compares your installed version against the latest available on your configured tier and reports whether an update is available.

Method 2: cPanel Change Log

Visit the official cPanel change log to see the latest release for each tier:

https://docs.cpanel.net/changelog/

Compare the version listed there against your installed version.

Method 3: WHM Update Center

In WHM, navigate to WHM → cPanel → Upgrade to Latest Version (or search “Update” in the navigation). This page shows:

• Your current version
• The latest available version on your tier
• A one-click update button

Method 4: Check via /etc/cpupdate.conf

cat /etc/cpupdate.conf

This file shows your server’s configured update tier and settings:

CPANEL=RELEASE
RPMUP=daily
STAGING_DIR=/usr/local/cpanel

If CPANEL=RELEASE, your server automatically updates to the latest RELEASE tier build during scheduled maintenance windows.

---

How to Force a Manual cPanel/WHM Update

If you’ve confirmed your server is behind on its version — especially after a security advisory — you can force an immediate update:

/scripts/upcp --force

Warning: Always take a full server backup before forcing a cPanel update on a production server. While cPanel updates are generally smooth, they can occasionally cause unexpected behavior with heavily customized configurations.

After the update completes, verify the new version:

/usr/local/cpanel/cpanel -V

Then restart the cPanel service daemon to ensure all new code is loaded:

/scripts/restartsrv_cpsrvd

---

Checking cPanel Version in Specific Scenarios

Checking Version on a Managed/Shared Hosting Server (No Root)

If you are on shared hosting with no SSH and no WHM access:

• Log into cPanel and scroll to the bottom footer — the version is displayed there
• Contact your hosting provider’s support team and ask: “What cPanel version is my account running on?”
• Most support teams will provide this within minutes

Checking Version via WHMCS (for Hosting Resellers)

If you manage servers via WHMCS:

1. In WHMCS admin, navigate to System Settings → Servers
2. Click on the server you want to check
3. Click Test Connection — this queries the WHM API and displays the detected cPanel version

Checking Version Before a Vulnerability Patch

If a cPanel security advisory has been released (check https://support.cpanel.net/hc/en-us/sections/200386544):

1. Note the patched version numbers listed in the advisory
2. Run /usr/local/cpanel/cpanel -V on each server
3. If your build number is lower than the patched version, run /scripts/upcp --force immediately
4. Restart cpsrvd after updating: /scripts/restartsrv_cpsrvd

Why Staying Updated on cPanel/WHM Is a Security Imperative in 2026

The significance of version checking has changed dramatically. In 2026, cPanel servers have been under sustained, active attack:

• A critical zero-day authentication bypass (CVE-2026-41940) was exploited in the wild for over two months before a patch was released, affecting servers running cPanel across every supported version
• Three additional high-severity CVEs were patched in May 2026, with two rated CVSS 8.8, covering arbitrary code execution and privilege escalation
• A further round of critical patches was released on May 13, 2026, affecting versions 86 through 136 including CloudLinux builds

Security researchers have noted that the gap between a CVE being published and working exploit code appearing in the wild is shrinking — sometimes measured in hours rather than weeks. For server administrators running cPanel, version awareness is now a continuous operational responsibility, not a quarterly check.

Best practices for staying current:

• Configure automatic updates on the RELEASE tier for production servers (CPANEL=RELEASE in /etc/cpupdate.conf)
• Subscribe to cPanel’s security announcement mailing list at https://cpanel.net/security/
• Monitor the cPanel Security Advisories page regularly
• After any security advisory, verify your version and patch within 24 hours
• Maintain a server inventory documenting the cPanel version on each managed server

Frequently Asked Questions

Q: What is the latest cPanel/WHM version in 2026? As of May 2026, cPanel version 136 is the current RELEASE tier production version. Version 138 is available on the EDGE tier for testing. The specific latest build within v136 can change frequently due to security patches — always check /usr/local/cpanel/cpanel -V against the official changelog at docs.cpanel.net/changelog for the current build number.

Q: Can I check the cPanel version without SSH or WHM access? Yes. If you have a cPanel account, scroll to the bottom footer of any page in the cPanel dashboard — the version is displayed there. Alternatively, contact your hosting provider’s support team.

Q: My cPanel version is old — is it dangerous? Potentially yes. cPanel has issued multiple high-severity security patches in 2026, with some vulnerabilities actively exploited before patches were available. If your version predates recent security patches, contact your hosting provider immediately to request an update, or run /scripts/upcp --force if you have root access.

Q: How do I find the cPanel version file location? The primary version file is at /usr/local/cpanel/version. A secondary reference may exist at /var/cpanel/version. Both contain the version string in plain text.

Q: What is the difference between cPanel version and build number? The version (e.g., 11.136.0) indicates the feature release. The build number (e.g., build 9 or the last segment 11.136.0.9) indicates the specific compiled release within that version — important for identifying whether a specific security patch has been applied.

Q: How do I check cPanel version on multiple servers at once? Use a one-liner with SSH and a server list:

for server in server1.com server2.com server3.com; do
  echo -n "$server: "
  ssh root@$server "cat /usr/local/cpanel/version"
done

Or use an automation tool like Ansible:

ansible all -m shell -a "cat /usr/local/cpanel/version"

Q: Why does my cPanel version show 11.x when I thought cPanel was on version 136? The 11 prefix is the long-standing major version number for cPanel and has not changed in many years. When people refer to “cPanel 136” or “version 136,” they mean the minor version — the second segment in the full version string 11.136.x.x.
