CVE-2022-0760Public exploitNetwork attack vector

Unauthenticated SQL injection via unvalidated post_id

Published Mar 21, 2022 · Updated Aug 2, 2024

SQL injection in QuantumCloud Simple Link Directory before 7.7.2 allows remote attackers to execute arbitrary SQL via post_id. The qcopd_upvote_action AJAX handler inserts the attacker-controlled post_id value into a SQL statement without validation or escaping. The public proof of concept confirms time-based blind injection without authentication; broader database effects depend on the WordPress database account permissions.
