User data disclosure via unauthenticated REST enumeration
Published Mar 13, 2024 · Updated Apr 8, 2026
Information exposure in MasterStudy LMS 3.2.10 and earlier allows remote attackers to read registered users' usernames and email addresses. The users REST route in _core/lms/route.php invokes StmUser enumeration without first enforcing an authorization check. No account or user interaction is required; the response discloses identity data but does not modify user records.
