Jleyva Moodle-block Configurablereports vulnerabilities

Configurable Reports block for Moodle (moodle-block_configurablereports) before 5.3.1 contains an sql injection vulnerability in report_sql::prepare_sql() via the filter_var request parameter of viewreport.php. Low-privileged users permitted to view reports using the %%FILTER_VAR%% placeholder can inject subqueries or UNION SELECT to read arbitrary database tables, including user password hashes.

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.
