CVE-2025-71337

Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Flowise ausnutzen, um Sicherheitsvorkehrungen zu umgehen und sich so Zugriff auf Konten zu verschaffen.

### Summary Unverified Email Change - Email as part of Credential / Unverified Account Recovery Channel Change The application allows changing the account email address (used as a login identifier and/or password recovery address) without verifying the requester’s authority to make that change (no confirmation to the old email, no authentication step). Because email often functions as a credential or recovery channel, unverified email changes enable attackers to take over accounts by switching the account’s recovery/login address. ### Details Occurence - code: https://github.com/FlowiseAI/Flowise/blob/main/packages/ui/src/views/account/index.jsx#L211 Remote and physical scenarios can be considered. ### PoC **Repro steps:** 1. As logged in user https://cloud.flowiseai.com/account scroll down to 'Profile' section 2. Change email to the new email 3. Notice Unverified Password Change (authenticated change without current password) Later this email is needed as credentials to log in or reset password feature. **POC:** Email changed, and notice "Profile updated" message. **Screenshot** <img width="329" height="357" alt="secbug" src="https://github.com/user-attachments/assets/d3c77835-35bb-47dc-8cd2-83e4e266e5a4" /> ### Impact Full account takeover (ATO) of affected accounts (loss of confidentiality and integrity of account data). User account recovery mechanisms (password reset flows tied to email) can be bypassed or abused if combined with this issue and the second one which I've reported (similar security issue with the password - part of credentials).
