We are writing to let you know about two recently disclosed security vulnerabilities in PHP, a programming language used by a very large number of web applications across the industry. The issues were publicly announced on 21 October 2026 and affect organisations worldwide, not only Zinc.
Our engineering and security teams are already working on this. We have reviewed where PHP is used across our services and have prioritised our response accordingly.
We are putting additional protective measures in place and monitoring our services closely for any unusual activity.
If you have any questions, please get in touch with our support team via zinc.support.
Kind Regards, Zinc Systems
