Learnosity Status

Identified: The Learnosity Demos site has been temporarily taken offline as a precautionary measure while we address recently disclosed critical vulnerabilities in PHP (CVE-2026-109618 and CVE-2026-109619).

We are working to restore access as soon as the necessary security updates have been applied and verified.

This maintenance is limited to the Demos site and does not affect Learnosity's production APIs or services.

Resolved: As of 18:00 UTC, after a long period of additional monitoring without further issue, we are resolved this incident affecting Enhanced Math Scoring in US-East-1.

Learnosity Support and Systems Engineering teams will follow up with a post mortem once we have completed root cause analysis and finalized any next steps or preventative measures required.

Please reach out if you have any questions or concerns.

Monitoring: As of 15:45 UTC, mitigation measures have successfully kept the submission queue clear, and scoring has continued to operate normally. Submissions received during the period of degraded performance were captured, and no data was lost. All other APIs remain operational.

We are continuing to investigate the root cause and will share an incident postmortem once our investigation is complete. In the meantime, we are entering an additional monitoring period to confirm continued stability before closing the incident.

Investigating: As of 15:00 UTC, we are still investigating the short-lived degraded performance of our Enhanced Math Scoring service, but have not seen significant errors or delays for more than an hour. The backlog of sessions awaiting scoring cleared quickly, and submissions continue to be scored normally. All other APIs remain unaffected.

Learnosity Support and Systems Engineering teams are continuing to actively investigate the issue, and will follow on with an update and resolution as soon as possible.

Investigating: As of 13:20 UTC, we started seeing scoring delays with our Enhanced Math Scoring service in the US-East-1 region. No data loss has been observed and all sessions have ultimately been scored. As a knock-on effect, the Data API Scoring endpoint is experiencing intermittent availability issues. No authoring or assessment delivery has been affected.

Learnosity Support and Systems Engineering teams are actively investigating the issue, and will follow on with an update and resolution as soon as possible.
