Student data was accessed, including students' names and birthdays, CPS said.

The district believes all current students and all former students dating back to the 2017-2018 school year were impacted.

"Importantly, no Social Security numbers, no financial information, and no health data were involved in this incident," a CPS release read in part. "At this time, there is no evidence to suggest that any student data has been misused. No staff information was involved in this incident."

CPS is working with investigators.

No further information was immediately available.
