Mixpanel recently addressed a data ingestion issue that affected a small subset of customer projects, which involved the Autotrack feature inadvertently sending password field values due to a change in the React JavaScript library. Upon discovering the issue, Mixpanel took immediate steps to secure and delete the unintentionally collected data and implemented a server-side filter to prevent further data receipt. The company has reached out to affected customers, offering detailed metadata about the incident and advising them to update their JavaScript SDKs. Mixpanel has committed to enhancing its privacy and security measures by incorporating additional reviews during product development, conducting in-depth audits, operationalizing response tools, and exploring data detection capabilities. The Autotrack feature has been disabled by default for new projects, and Mixpanel is reviewing its products to ensure they meet high privacy and security standards.
