Changelog

We have released released Private Location Monitoring (PLM) v5.6, which includes important security updates addressing the following PHP vulnerabilities:

• CVE-2026-109618

• CVE-2026-109619

The updated image includes Ubuntu's patched PHP 8.1 packages (8.1.2-1ubuntu2.28), along with additional Ubuntu security and maintenance updates.

We strongly recommend that all customers running Private Location Monitoring upgrade to v5.6 as soon as possible. The updated image is available on Docker Hub:

uptimecom/uptime-private-location:5.6

The latest tag has also been updated.

We've verified the updated PHP packages and completed functional testing of the new image.

We recommend upgrading to v5.6 and recreating your container to ensure the patched image is running. Should you have any questions, please contact support@uptime.com. For general information on Private Location Monitoring, see our Github.

We have added a new WhatsApp integration to Uptime.com, allowing you to receive alert and recovery notifications directly via WhatsApp.

Once configured, Uptime.com will send a WhatsApp message when an alert is raised and a recovery message when the check recovers.

To set it up, navigate to Notification > Integrations, search for WhatsApp, and click Add. From there, enter a name, assign a contact, and add the recipient’s phone number.

For more information, please see our documentation on Configuring Whatsapp.

We have added the ability to use a Custom User Agent field to the Authentication & Settings step in Transaction Checks, allowing you to define a custom User Agent string for your check.

To ensure correct legitimate usage, to enable this feature you must contact us at support@uptime.com. Once enabled, navigate to your Transaction Check, open the Check Steps tab, click Add Step > Authentication & Settings, and expand the step to set your custom User Agent.
