The Library Management System – Manage e-Digital Books Library WordPress plugin (owthub) is vulnerable to SQL Injection via the 'value' parameter in the owt_lib_handler AJAX action in all versions up to 3.1. The issue stems from insufficient escaping of user input and lack of proper SQL query preparation, enabling authenticated administrators to inject additional SQL commands. This can lead to unauthorized disclosure of sensitive database information. The vulnerability has a CVSS 3.1 base score of 6.8 (medium severity), with network attack vector, low attack complexity, and requiring high privileges. No patch or official fix has been documented yet.

An attacker with Administrator-level access can exploit this vulnerability to execute arbitrary SQL queries appended to existing ones, potentially extracting sensitive information from the database. The vulnerability does not affect system availability or integrity but compromises confidentiality. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Administrator-level access to trusted users only and monitor for suspicious activity related to the owt_lib_handler AJAX action. Avoid exposing this plugin on publicly accessible sites where possible.
