Unauthenticated credential disclosure via unsanitized login response
Published May 6, 2026 · Updated May 6, 2026
Information disclosure in Flowise 3.0.0 through 3.0.12 allows remote attackers to retrieve credential material through account APIs. The Login and saveInviteAccount paths in packages/server/src/enterprise/services/account.service.ts return complete user objects without removing credential, tempToken, and tokenExpiry fields. Unauthenticated login or invite requests can expose bcrypt password hashes and live reset data for arbitrary accounts, including privileged accounts.
