The owthub Library Management System WordPress plugin versions up to 3.2.1 suffer from an SQL Injection vulnerability (CWE-89) due to insufficient escaping and lack of proper query preparation of the user-supplied 'bid' parameter. This allows unauthenticated remote attackers to append malicious SQL commands to existing queries, potentially exposing sensitive data from the backend database. The CVSS 3.1 base score is 7.5, reflecting a high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. There is no vendor-provided patch or official fix information available at this time.

Successful exploitation allows unauthenticated attackers to extract sensitive information from the database by injecting arbitrary SQL commands via the 'bid' parameter. The vulnerability does not impact integrity or availability directly but compromises confidentiality of data stored in the database. 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, users should consider disabling or restricting access to the vulnerable plugin to prevent exploitation. Applying web application firewall (WAF) rules to block SQL injection attempts targeting the 'bid' parameter may provide temporary mitigation.
