changedetection.io - Missing Authentication on /api/v1/full-spec Discloses Full OpenAPI Schema

AI Analysis

No AI analysis yet.

Description

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.
