A bug in Linear caused user-specific data to be accessible to wrong users within the same workspace from 12:07-1:10am UTC on March 24, with limited exposure and no cross-workspace access. The incident also affected inbox notifications, which were incorrectly deleted for some users, and notification emails sent during the timeframe may have contained other users' data. Linear remediated the core issue, logged out all mobile sessions, force-reloaded desktop/web clients, and ran restoration jobs for the affected notifications.
