CVE-2023-2921Public exploitNetwork attack vector

Subscriber SQL injection via unsanitized idLink parameter

Published Jun 6, 2025 · Updated Jun 9, 2025

SQL injection in KaizenCoders URL Shortify 1.6.8 and earlier allows remote authenticated users to read database data via AJAX. The valid_link AJAX action passes the attacker-controlled idLink parameter into an SQL statement without adequate sanitization, escaping, or preparation. Subscriber-level access is sufficient, and the published time-delay payload confirms blind query control that can disclose database contents.
