Guest OAuth token disclosure via getAccessToken

Published Aug 11, 2026 · Updated Aug 11, 2026

Information disclosure in Typebot before 3.17.0 allows remote authenticated users to obtain reusable Google Sheets OAuth tokens. The sheets.getAccessToken ORPC handler accepts workspace read access, decrypts the selected credential, refreshes it, and returns the raw bearer token. Guest workspace membership and an existing Google Sheets credential are required; the token permits Google API access within the credential's granted scopes.
