Scheduled - We will be performing scheduled maintenance at our TEB4 data center as part of ongoing facility and network infrastructure upgrades.

Maintenance will be carried out in phases to minimize service disruptions. Affected servers will experience a temporary interruption of service, with expected downtime of up to 3 hours per server.

As maintenance windows are finalized, additional updates will be posted identifying the affected servers and their scheduled dates and times.

We will continue to provide updates throughout the maintenance process until all work has been completed.

Mailbaby zone4 maintenance
Completed - The scheduled maintenance has been completed.
Nov 9, 15:36 EST
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Nov 9, 11:41 EST
Scheduled - As part of the TEB4 maintenance today zone4 for mailbaby will be temporarily offline. Mailbaby runs under a 4 zone system, and the other three zones will handle all deliveries during this time. Emails queued with in zone4 however, will not reattempted delivery until the zone is back online. Queued emails that are still in the zone are emails that tend to be from the remote server being down, or greylisted emails that would be delayed in all cases.

Scheduled - Scheduled - Maintenance Window: (72-hour duration)

Overview:
Over the next 72 hours, our engineering team will perform rolling kernel updates on a specific group of KVM and webhosting host servers. This maintenance is required to patch the current system base and maintain overall infrastructure security.

Expected Impact:
To minimize disruption, we are updating and rebooting these servers one at a time. If your applications or virtual machines operate on an affected host, you will experience a brief interruption in connectivity when that specific machine restarts to apply the new kernel.

Because this is a rolling update across a 72-hour window, the entire cluster will not go offline at once. We expect downtime for any individual host to be limited to the time it takes to complete a standard reboot.

The following systems are scheduled

storage-kvm10.lax1
storage-kvm6200
storage-kvm6100
storage-kvm6000
storage-kvm5800
storage-kvm5700

Upcoming PHP Security update
Resolved - This incident has been resolved.
Nov 3, 09:53 EST
Update - A further security vulnerability was found in PHP and has been assigned CVE-2026-115560. More info at https://www.php.net/archive/2026.php#2026-10-23-1

All webhosting servers have the recommended mitigation enabled.
Oct 28, 19:12 EDT
Update - ea-php (cPanel EasyApache 4) builds with the PHP.net version numbers are now in the stable repositories:
- ea-php82: 8.2.35-1, for CloudLinux OS 7, 8, 9, 10 and CloudLinux OS for Ubuntu 22.04
- ea-php83: 8.3.36-1, for CloudLinux OS 7, 8, 9, 10 and CloudLinux OS for Ubuntu 22.04
- ea-php84: 8.4.27-1, for CloudLinux OS 8, 9, 10 and CloudLinux OS for Ubuntu 22.04
- ea-php85: 8.5.12-1, for CloudLinux OS 8, 9, 10 and CloudLinux OS for Ubuntu 22.04

Previous versions were backported. The new releases show the updated versions.
Oct 24, 08:13 EDT
Update - Update: Security Patches Deployed for PHP Vulnerabilities (CVE-2026-109618 / CVE-2026-109619)

We have deployed security updates across our cPanel, DirectAdmin, and Webuzo hosting environments to address the recent PHP vulnerabilities.

Shared Hosting Proactive Mitigations
Before the official PHP updates were even released, we proactively forced session.upload_progress.enabled=0 across all shared hosting servers as a partial mitigation. We also deployed custom Web Application Firewall (WAF) rules to inspect and protect multi-part uploads against this exploit. These servers are now receiving the full PHP patches as outlined below.

cPanel Servers
For cPanel systems, the fixes are applied as backports. This means your PHP version number will not change to the latest upstream release (for example, ea-php84 remains at 8.4.26 instead of showing 8.4.27).

To confirm the fix is active on a cPanel server, you need to check the package changelog for the CVE IDs rather than looking at the PHP version number. You can verify this via SSH using the following command (replace ea-php84 with your installed version):rpm -q ea-php84-php-cli --changelog | grep -E 'CVE-2026-(109618|109619)'

DirectAdmin Servers
On DirectAdmin, modern PHP branches have been updated to the fully patched upstream releases: 8.5.12, 8.4.27, 8.3.36, and 8.2.35. For older, legacy PHP versions (5.6 through 8.1), the security fixes have been successfully applied as custom patches through CustomBuild.

Webuzo Servers
For Webuzo environments, all PHP packages spanning versions 5.6 through 8.5 are available for updates by logging into webuzo

Manual Workaround for Unmanaged Servers
If you are running an unmanaged server and cannot apply the PHP updates immediately, you can temporarily mitigate the vulnerability by disabling session upload progress. To do this, add or update the following line in your active php.ini file:session.upload_progress.enabled=0 while updates applied.
Oct 22, 07:54 EDT
Update - directadmin legacy and cloudlinux are patched and going through final checks.
Oct 21, 20:14 EDT
Update - directadmin storage systems (with out cloudlinux) have been patched
Oct 21, 20:10 EDT
Update - All cpanel systems ea-php* packages have been updated. However some include back ports such as ea-php84 is 8.4.26, not 8.4.27.
Oct 21, 19:32 EDT
Update - Cpanel has released 8.5.12, 8.4.27, 8.3.36, 8.2.35, along with the backported versions 8.1.34,8.0.30, and 7.4.33 and these are now being applied.
Oct 21, 11:41 EDT
Update - Directadmin custombuild is available: This moves PHP 8.5, 8.4, 8.3, 8.2 to latest version, and adds patches for PHP 8.1, PHP 8.0 and PHP 7.4

Please be aware PHP lower than 7.4 will be removed, if installed through custombuild at this time. PHP selector from cloudlinux will patch via alt-php.
Oct 21, 10:18 EDT
Update - Imunify360 has release ModSecurity ruleset 8.83 which targets the PHP session upload progress handling of multipart requests, plus a telemetry rule to track related activity. All webhosting servers have been verified to be running this version.

Storage directadmin does not offer imunify360. These run modsecurity with owasp ruleset.
Oct 21, 08:27 EDT
Update - On shared hosting systems with in the last few hours
session.upload_progress.enabled = Off
Has been set off with in php.ini as all as in litespeed under the main config file using php_value. This closes a possible part of of the exploit, but officially this mitigation does not come directly from PHP devs.
Oct 21, 07:34 EDT
Update - The official PHP project will likely not provide security patches for versions older than PHP 8.2.

Servers running cPanel or DirectAdmin with CloudLinux utilize HardenedPHP and will receive these patches over time. Standard DirectAdmin servers without CloudLinux do not currently support HardenedPHP, though we are actively consulting with the CloudLinux team to determine if standalone Imunify360 servers can utilize it.

Additionally, if the exploit is within PHP-FPM, servers running LiteSpeed are likely unaffected.

Depending on the severity of the issue, sites on non-CloudLinux systems without HardenedPHP may be required to update to PHP 8.2 or higher, or migrate to a CloudLinux system (which will require an IP address change).
Oct 20, 18:47 EDT
Investigating - An upcoming PHP security update is planned to be released tomorrow - https://www.php.net/archive/2026.php#2026-10-20-1

No further information is available at this time.
