Summary

The Visualizer WordPress plugin before 4.0.7 does not properly authorise access to the configuration of its charts, allowing users with the Contributor role and above to read the full configuration of any chart on the site, including charts the Visualizer WordPress plugin before 4.0.7's own interface denies them, and to retrieve every chart's configuration in a single request. The disclosed configuration can include the credentials of a remote data source a chart reads from.
