Configurable Reports block for Moodle before 5.3.0 contains an authorization bypass vulnerability that allows authenticated users to read restricted reports through the block_configurable_reports_get_report_data web service. When check_permissions fails, the function only adds a warning and still returns the full report table, letting any logged-in user supply arbitrary report ids to read SQL reports over user and grade data.
