Security Update – PHP Vulnerability

We are aware of the recent critical PHP security vulnerabilities highlighted by the National Cyber Security Centre (NCSC) on 21st October 2026.

We would like to reassure customers that our main platforms, 4Matrix Cloud and 4Matrix Fusion, do not use PHP and are therefore not directly affected by these vulnerabilities.

PHP is used within some of our supporting systems, including our customer support ticketing and billing systems. Our desktop application also communicates with our sales system for licence verification. These systems do not store customers' payment details or sensitive information as part of the licence verification process.

We have been in contact with our hosting provider, Krystal, who has confirmed that the necessary security fixes have been applied to address the reported vulnerabilities.

No action is required from our customers in relation to this advisory.

We take the security of our systems and customer information seriously and will continue to monitor security developments and work with our hosting provider to maintain appropriate protections.

What is a series?

A series is a snapshot of performance - for example a "Y11 Autumn 1" series may refer to teacher assessments that were taken before Autumn half term.

It is important to note that each series can only contain one grade per pupil per subject. A typical KS4 assessment cycle might therefore include multiple Predicted Grade/Working Grade series, a target series, mock exam series and a results series.

All of these data points can imported into 4Matrix as a Series. There is no limit to how many series you can import. 

This will provide an analytical record of performance using a ‘point analysis’ technique, i.e. several series of data about estimated grades collected of twice per term, and forming a record of movement over an academic year. Here are just some examples:

  • Performance Tracking tool will show headline results for any selection of series, across multiple cohorts and/or within a single cohort to track trends

  • The Series Analysis tool will show the differences between any series for a selected cohort of pupils

  • The Series Comparison tool will show the movement of grades towards the target grades

  • The Progress Graph tool will show trajectories for every pupil based on national chances tables, against which their progress can be plotted, and targets set
