{"id":"CVE-2026-71203","summary":"changedetection.io: Missing Authentication on /api/v1/full-spec Discloses Full OpenAPI Schema","details":"changedetection.io's REST API resources are protected by an @auth.check_token decorator validating the caller's x-api-key header, except the Spec resource registered at /api/v1/full-spec (changedetectionio/api/Spec.py), whose get() method carries neither @auth.check_token nor @validate_openapi_request. An unauthenticated client can retrieve the full merged OpenAPI schema (all endpoint paths, parameters, and registered processor plugins) even when API access control is enabled and every sibling /api/v1/* route correctly requires the key.","modified":"2026-08-06T03:48:34.442427945Z","published":"2026-08-05T06:58:56.911Z","database_specific":{"cna_assigner":"TuranSec","cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71203.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71203.json"},{"type":"PACKAGE","url":"https://github.com/dgtlmoon/changedetection.io"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71203"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dgtlmoon/changedetection.io","events":[{"introduced":"baae46deede1c7ab4a5b2a6a49f5338b495c694c"},{"last_affected":"baae46deede1c7ab4a5b2a6a49f5338b495c694c"}],"database_specific":{"extracted_events":[{"introduced":"0.55.7"},{"last_affected":"0.55.7"}],"source":"AFFECTED_FIELD"}}],"versions":["0.55.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71203.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
