Mathspace Data Breach Exposes Over 1 Million People

01What broke

SecurityWeek reports: Mathspace Data Breach Exposes Over 1 Million People. Hackers stole the information of students, teachers, staff, and parents/guardians from a self-hosted Metabase instance. The post Mathspace Data Breach Exposes Over 1 Million People appeared first on SecurityWeek .

Mathspace, an online mathematics program for students, has disclosed a data breach that impacts over 1 million individuals. The incident, it says, was discovered last week, roughly three weeks after hackers compromised its self-hosted Metabase instance using a known vulnerability.

02Who is exposed

The security defect, tracked as CVE-2026-72898 (CVSS score of 10/10) and described as an SQL injection issue, was patched on August 6, after it had been exploited in the wild as a zero-day. Shortly after the patches were released, the notorious extortion group ShinyHunters claimed responsibility for hacking Metabase.

03What to do now

Mathspace failed to escalate Metabase’s critical advisory to prioritize patching and upgraded its instance on August 29, more than two weeks after hackers hit it. See the full write-up from SecurityWeek via the source link for quotes and complete context.

“Our investigation identified unauthorised access dating back to 10 August 2026, Australian Eastern Standard Time. Furthermore, Mathspace did not complete the compromise checks Metabase had recommended, and did not identify the intrusion upon applying the update.

04How the issue works

“We are investigating why the initial advisory was not escalated and why those checks were not completed sooner. We are changing both processes as part of our incident response,” the online platform says.

05What is still unknown

Mathspace has taken its Metabase instance offline, revoked API keys, disabled the database access accounts, changed passwords, and exported the logs for investigation. See the full write-up from SecurityWeek via the source link for quotes and complete context.
