The current sources do not mark it as known exploited. The current feed maps dgtlmoon/changedetection.io (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
