CVE-2026-42142Public exploitNetwork attack vectorHinoki check available

Authenticated OAuth credential disclosure via missing membership check

Published Aug 11, 2026 · Updated Aug 11, 2026

Missing authorization in Typebot 3.16.1 and earlier allows remote authenticated users to access other workspaces' Google Sheets data. The handleGetSheets handler accepts workspace and credential identifiers, decrypts the matching OAuth credential, and fetches sheet metadata without checking workspace membership. A valid account and the target identifiers are required; exposure includes OAuth secrets, sheet names, sheet IDs, and column headers.
