changedetection.io is a Website change detection and monitoring service
Affected versions of this package are vulnerable to Access Control Bypass via the settings save handler, which constructs an update dictionary from form data and merges it into stored application settings. An attacker can gain unauthorized access to sensitive information and modify configuration by sending a crafted POST request that omits the api_access_token_enabled field, thereby disabling API key enforcement for the REST API.
