CyberRota Analysis
AI-GeneratedThe Speakr web application is vulnerable to a CSRF bypass due to improper token authentication and permanent exemption of certain views from CSRF protection, allowing attackers to exploit this flaw to modify user profiles and administrative settings. This vulnerability can be exploited by a network-reachable attacker with control over a sibling subdomain, enabling unauthorized changes without proper validation. Organizations using Speakr versions prior to 0.8.21-alpha should prioritize patching this issue to mitigate potential unauthorized access and data manipulation risks.

Original NVD Description
Speakr is a personal, self-hosted web application designed for transcribing audio recordings. Prior to 0.8.21-alpha, the csrf_exempt_for_api_tokens() before_request hook in src/app.py calls csrf.exempt(view_func), permanently adding the selected view to Flask-WTF's process-global exemption set. The is_token_authenticated() function in src/utils/token_auth.py calls extract_token_from_request() and treats any present token, including request.args.get('token'), as authenticated without hashing the token, querying the database, or checking validity. A network-reachable attacker can therefore send a false token to disable CSRF protection for the targeted view for the worker lifetime. Because the exemption applies to the view function across HTTP methods, a cross-origin GET to /account with a query token can poison CSRF state for a later state-changing POST without triggering CORS preflight. This browser sequence requires attacker-controlled content on a sibling subdomain under the documented cookie conditions. The bypass can modify profile data, custom prompts, transcription settings, preferences, and administrative status through routes such as admin_toggle_admin. The change_password route also skips current-password verification when current_user.password is empty, allowing the chain to set a local password on an SSO-only account and bypass SSO. This issue is fixed in version 0.8.21-alpha.
