VIR risk

6.3

Description

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.
