Result data disclosure via unscoped findResult query
Published May 22, 2026 · Updated May 22, 2026
Missing authorization in Typebot 3.15.2 and earlier allows remote authenticated users to read cross-typebot result data via startChat. The bot engine's findResult query accepts a client-supplied resultId but looks up an unarchived result without constraining it to the current typebotId. Exploitation requires a valid cryptographically random CUID2 result ID, rememberUser enabled, and matching variable names; exposed data is limited to prior answers, variables, and hasStarted.
