CVE-2026-113607: Moodle Configurable Reports block authorization bypass

CVE-2026-113607 · Severity: medium · CVSS 6.5 · Published 2026-10-20

The Configurable Reports block for Moodle is an extension that lets instructors create custom reports on course data. An authorization flaw allows any logged-in user to read restricted reports containing sensitive student grades and user information by directly calling the web service with arbitrary report IDs, bypassing permission checks. This could expose private academic and personal data to unauthorized users within a Moodle instance.

Vendors: Moodle.

Technical details

The block_configurable_reports_get_report_data web service endpoint fails to enforce authorization checks: when check_permissions() returns false, the function only logs a warning but continues to process and return the full report table. An authenticated attacker can pass arbitrary reportid values to retrieve SQL reports over sensitive data (users, grades). The vulnerability requires user authentication and network access to the Moodle instance.
