Team Textpattern is pleased to announce the release of Textpattern CMS version 4.8.8, available for immediate download and deployment. Textpattern 4.8.8 adds support for PHP 8.1, addresses a security issue, and offers additional minor improvements to the user experience.
If you have a Textpattern website, we recommend upgrading to Textpattern 4.8.8 to fix a reported security issue. Many thanks to Paul Ritchie at Pentest Ltd for responsibly reporting an issue relating to article preview and plugin upload functionality. We are grateful for Paul’s thorough report in outlining the issue, which allowed Textpattern developers to efficiently reproduce the issue, isolate a fix and resolve it. Versions of Textpattern prior to 4.8.8 are affected by this issue, and upgrading is highly recommended.
Pentest will be publishing an article on their site detailing the issue, we will update this post with further details when we have them.
Update: Pentest have published an article outlining the issue in more detail – Leveraging XSS to get RCE in Textpattern 4.8.7

Before you make any changes, please refer to the accompanying release notes in HISTORY.txt to ensure you understand what has changed in this release, along with any versions released beforehand that may have been skipped. You can check your current Textpattern version from the bottom of any page on the admin-side.

You can show your appreciation by sponsoring Textpattern on GitHub or supporting Textpattern on Open Collective. Alternatively, you can donate to Team Textpattern with PayPal.
We have a friendly forum for a Textpattern sites showcase – tell us what you’ve made with Textpattern, we’d love to hear from you. Even a ‘hello!’ or ‘thanks!’ helps us to gauge how far Textpattern has travelled, so don’t be a stranger.
You can download Textpattern from textpattern.com using the following links, or from Textpattern v4.8.8 on GitHub. Please take a moment to ‘star’ Textpattern’s repositories on GitHub if they are of interest to you. This really helps us out.
Please note: to fully utilise Textpattern’s multi-site capabilities, please download the
.tar.gz archive as it includes the multi-site scaffold.
The Textpattern demo has been updated to offer Textpattern test drives in complete safety. The demo sites are rebuilt every few hours using the Textpattern auto-installer.
Textpattern 4.8 requires a minimum of PHP 5.5 as part of the system requirements, though a vendor-supported PHP version is highly recommended. At the time of writing, PHP 8.0 & PHP 8.1 have active and ongoing support. PHP 7.4 has extended security support until 28 November 2022. All PHP versions before PHP 7.4 are no longer supported by the vendor. Please refer to PHP Supported Versions for up-to-date schedules.
If you are upgrading Textpattern from a version prior to 4.8.0, please note the SimpleXML PHP extension is now required. Most PHP instances have this built-in and enabled already. Check with your web host if you have any doubts.
Please note: we will increase the minimum PHP and MySQL version requirements for Textpattern 4.9. More details will be provided in due course.
Installation and upgrade
Please ensure you log out of the admin side prior to upgrade, perform and verify a full site backup (database and files, including any file/image uploads), and refer to the
README.txt file in the download archives for detailed instructions. The vast majority of Textpattern upgrades are smooth sailing and happen without incident, but on the rare occasion something does go astray it’s preferable to safely restore the known-good version from your full site backup and troubleshoot any issues while your site continues to be available.
