CVE-2023-53982Public exploitNetwork attack vector

Database information disclosure via unsanitized storage identifier

Published Dec 23, 2025 · Updated Dec 23, 2025

SQL injection in PMB Services PMB 7.4.6 allows remote attackers to read database data through the OPAC ajax.php storage request. The storage handler incorporates the id query parameter into a database query without neutralizing SQL syntax, enabling conditional SLEEP expressions and time-based extraction. The public OPAC endpoint accepts the crafted request without authentication; demonstrated consequences are database-query manipulation and information disclosure.
