Typebot · Typebot · CVE-2026-39967
**Name of the Vulnerable Software and Affected Versions**
TypeBot versions prior to 3.16.0
**Description**
An issue in the bot engine's `findResult` query fails to filter results by `typebotId`. This allows an authenticated user to load result data, including user answers and variable values, from a different typebot by providing a foreign `resultId` to the 'startChat' endpoint. Successful exploitation can expose personally identifiable information (PII) such as names, emails, and phone numbers, as well as session variable values and the `hasStarted` flag. Exploitation requires `rememberUser` to be enabled and matching variable names in the current typebot. The use of CUID2 (cryptographically random 24-character IDs) makes brute-forcing the `resultId` infeasible.
**Recommendations**
Update to version 3.16.0.
