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.

How do I change the qualification that a subject is mapped to?

Go to Admin > Edit Subjects and select the subject from the list on the left.

To change for all series

This change will affect all series where the subject is in use, as shown in the Results panel in Edit Subjects.

In the top right of the Mapped Qualification panel, go to Change Map. On smaller screens, this option may be hidden via a small arrow next to Edit Qualification.

A pop-up will appear asking you to search for the new QAN. You can search by name or by QAN. If using the QAN, be sure to type the 8 digits without any '/' symbols.

A Grade Match box will appear asking you to confirm that it's correct - the only time that this may be cause for concern is if you are trying to change from a GCSE grading structure to a BTEC or vice versa, or to a qualification with additional (or fewer) grades. If this is the case then we strongly recommend that you re-import the data for this subject rather than convert the grades in order to avoid mistakes. This action cannot be undone.

After using this function you may need to merge subjects together using the Similar Subjects panel.

To change for the selected series

Make sure that the subject you want to change to has already been created in the left hand panel. Check the Other section in this list as well. If it is not there then create the subject using Add New Subject. Make sure the qualification has a unique name e.g. "Sport (voc) >2024"

Select the subject you want to change the mapping for and click Move (top right of screen). Select the subject you want to move it to using the drop down list and click Continue. As per above check the Grade Match box to make sure all grades are mapped correctly.
