CVE-2026-3734Public exploitNetwork attack vector

Unauthenticated manager-data disclosure via unchecked manager_id

Published Mar 8, 2026 · Updated Mar 8, 2026

Improper authorization in SourceCodester Client Database Management System 1.0 allows remote attackers to read manager data without authentication. The fetch_manager_details.php endpoint accepts a caller-controlled manager_id value and returns the corresponding manager and agent record without checking a session or the caller's authorization. Any network client that can reach the endpoint can enumerate internal manager and agent details; the published evidence does not establish write access through this endpoint.
