Schoolrunner production is back online and available as of 9:15pm CDT on October 21. We are continuing to work on restoring archive site access and expect that to be completed tomorrow, October 22. Thank you for your patience while the platform was in maintenance mode.
While Schoolrunner was offline, our engineers made configuration changes designed to reduce Schoolrunner's exposure to the recently disclosed PHP vulnerability. We tested these changes before restoring access. These measures significantly reduce the risk of exploitation, though no security measure can eliminate all risk. We are tracking the issue closely and will evaluate and apply a permanent fix as soon as one is available and can be deployed safely.

Investigating
Effective immediately, we have placed Schoolrunner in maintenance mode as a proactive security measure. No security incident has occurred on Schoolrunner, and we have no indication that any customer or student data has been accessed or affected. We expect Schoolrunner to be back online by Thursday, October 22, 2026 at 5PM Eastern. Please plan alternate paths for your processes tomorrow and notify your staff of the downtime.
A recently disclosed vulnerability in PHP, a programming language used widely across the internet, is affecting a large share of web applications worldwide, and attackers are exploiting it against vulnerable applications elsewhere. Schoolrunner has not been compromised. Out of an abundance of caution, we have taken Schoolrunner offline while our engineers assess our exposure. The protection of your data and your students’ information is our highest priority.
We understand that Schoolrunner is a mission-critical tool for your teams, and we sincerely regret the disruption this precaution causes. Our engineers are working around the clock to mitigate risk and restore access as quickly and safely as possible. We will send an update as soon as we have a confirmed timeline for restoring service. In the meantime, if you have questions or urgent needs, please contact our Support team at support@schoolmint.com.
