{"id":"CVE-2026-54510","summary":"Speakr: CSRF bypass via unauthenticated API token parameter in csrf_exempt_for_api_tokens hook","details":"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.","aliases":["GHSA-x4q4-3ww4-h329"],"modified":"2026-09-19T03:46:30.875983398Z","published":"2026-09-17T20:20:29.308Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-287","CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54510.json"},"references":[{"type":"WEB","url":"https://github.com/murtaza-nasir/speakr/releases/tag/v0.8.21-alpha"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54510.json"},{"type":"ADVISORY","url":"https://github.com/murtaza-nasir/speakr/security/advisories/GHSA-x4q4-3ww4-h329"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54510"},{"type":"FIX","url":"https://github.com/murtaza-nasir/speakr/commit/70e193e47b664bedf274f62aea14220f2a85a459"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/murtaza-nasir/speakr","events":[{"introduced":"0"},{"fixed":"70e193e47b664bedf274f62aea14220f2a85a459"},{"fixed":"5df6afdff18d21d4d6d2b0a6399f2c92e7df7916"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"0.8.21-alpha"}]}}],"versions":["v0.8.20-alpha","v0.8.19-alpha","v0.8.18-alpha","v0.8.17-alpha","v0.8.16-alpha","v0.8.15-alpha","v0.8.14-alpha","v0.8.13-alpha","v0.8.12-alpha","v0.8.11-alpha","v0.8.10-alpha","v0.8.9-alpha","v0.8.8-alpha","v0.8.7.2","v0.8.7-alpha","v0.8.6.1-alpha","v0.8.6-alpha","v0.8.5.1-alpha","v0.8.5-alpha","v0.8.4","v0.8.4-alpha","v0.8.3-alpha","v0.8.2-alpha","v0.8.1-alpha","v0.8.0-alpha","v0.7.2-alpha","v0.7.1-alpha","v0.7.0-alpha","v0.6.5-alpha","v0.6.4-alpha","v0.6.3-alpha","v0.6.2-alpha","v0.6.1-alpha","v0.6.0-alpha","v0.5.10-alpha","v0.5.9-alpha","v0.5.8-alpha","v0.5.7-alpha","v0.5.6","v0.5.5-alpha","v0.5.1-alpha","v0.5.0-alpha","v0.4.2-alpha","v0.4.1-alpha","v0.3.1-alpha","v0.2.1-alpha","v0.2.0-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54510.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:N"}]}
