{"id":"CVE-2026-71204","summary":"changedetection.io: Omitted Checkbox in /settings Save Silently Disables API Key Enforcement","details":"changedetection.io's /settings save handler builds an update dict from form.data['application'] and blind-merges it into the stored application settings via .update(). Because WTForms represents an unchecked checkbox as False rather than 'unchanged', and only the 'password' field is special-cased against this problem, a POST to /settings that omits the api_access_token_enabled field (e.g. a minimal scripted request) silently disables API key enforcement for the entire REST API, exposing the full watch list, history, and configuration to unauthenticated requests.","modified":"2026-08-07T03:30:57.297608076Z","published":"2026-08-05T06:59:00.078Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71204.json","cna_assigner":"TuranSec","cwe_ids":["CWE-284"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71204.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71204"},{"type":"PACKAGE","url":"https://github.com/dgtlmoon/changedetection.io"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dgtlmoon/changedetection.io","events":[{"introduced":"baae46deede1c7ab4a5b2a6a49f5338b495c694c"},{"last_affected":"baae46deede1c7ab4a5b2a6a49f5338b495c694c"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0.55.7"},{"last_affected":"0.55.7"}]}}],"versions":["0.55.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71204.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:L"}]}
