{"id":"CVE-2026-54510","aliases":["EUVD-2026-82427","GHSA-x4q4-3ww4-h329"],"status":"published","title":"Speakr: CSRF bypass via unauthenticated API token parameter in csrf_exempt_for_api_tokens hook","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.","severity":{"version":"3.1","score":7.1,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:N","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00215,"percentile":0.11944,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-287","CWE-352"],"published":"2026-09-17T20:20:29Z","modified":"2026-10-28T02:30:47Z","products":[{"vendor":"murtaza-nasir","product":"speakr"}],"references":[{"url":"https://github.com/murtaza-nasir/speakr/security/advisories/GHSA-x4q4-3ww4-h329","tags":["x_refsource_CONFIRM","exploit","advisory"]},{"url":"https://github.com/murtaza-nasir/speakr/commit/70e193e47b664bedf274f62aea14220f2a85a459","tags":["x_refsource_MISC","fix"]},{"url":"https://github.com/murtaza-nasir/speakr/releases/tag/v0.8.21-alpha","tags":["x_refsource_MISC","web"]},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54510.json","tags":["advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54510","tags":["advisory"]}],"sources":{"cve":[{"id":"CVE-2026-54510","title":"Speakr: CSRF bypass via unauthenticated API token parameter in csrf_exempt_for_api_tokens hook","description":"Speakr is a personal, self-hosted web application designed for transcribing audio recordings.
