CVE-2026-42142
TypeBot is a chatbot builder tool. Prior to version 3.17.0, the `handleGetSheets` API handler (`POST /api/sheets/getSheets`) does not validate workspace membership, allowing any authenticated user to access and decrypt another workspace's Google Sheets OAuth credentials and retrieve spreadsheet data (sheet names, IDs, column headers). Version 3.17.0 fixes the issue.
