Update - Open LMS has taken all customer sites offline as a preventative measure.
Why: Two critical zero-day vulnerabilities in PHP have been discovered and are being actively exploited. No mitigation is currently available, so taking sites offline is the only way to fully protect them. These vulnerabilities affect PHP-based websites worldwide and are not specific to Open LMS.
What's next: The PHP project expects to release patches today. As soon as they are available, we will apply them and bring sites back online.
