CVE-2026-12582 in Library Management System Plugin
Summary
by MITRE • 07/13/2026
The Library Management System WordPress plugin before 3.5.8 does not sanitize and escape a user-supplied parameter before using it in a SQL statement, allowing unauthenticated attackers to perform SQL injection and extract arbitrary data from the database, including user password hashes.

This vulnerability exists within a WordPress plugin for library management systems where version 3.5.8 and earlier contain a critical sql injection flaw that affects unauthenticated users. The issue stems from insufficient input validation and sanitization of user-supplied parameters before they are incorporated into database queries. Specifically the plugin fails to properly sanitize or escape a parameter that gets directly embedded into sql statements without adequate protection mechanisms.
The technical implementation of this vulnerability allows attackers to manipulate database queries through crafted input parameters that bypass normal security controls. When unauthenticated users submit malicious data through vulnerable endpoints, the plugin processes these inputs without proper sanitization measures, enabling attackers to inject arbitrary sql commands. This weakness specifically targets parameter handling in database operations where user input flows directly into query construction.
The operational impact of this vulnerability is severe as it provides attackers with unauthorized access to sensitive database information including user credential hashes and other confidential data. Since no authentication is required to exploit this flaw, attackers can systematically extract information from the database without detection. The exposure of password hashes represents a critical risk vector that could lead to account compromise and further system infiltration.
This vulnerability maps directly to common weakness enumeration CWE-89 which identifies sql injection flaws as a primary security concern in web applications. From an attack framework perspective this issue aligns with techniques described in the mitre att&ck framework under initial access and credential access phases where adversaries exploit software vulnerabilities to gain unauthorized data access. The lack of proper input validation creates a direct pathway for attackers to manipulate database operations and extract sensitive information.
Mitigation strategies should focus on implementing proper parameterized queries and input sanitization mechanisms throughout the plugin codebase. All user-supplied parameters must be properly escaped or validated before database integration using prepared statements or equivalent protection methods. Regular security audits should verify that all database interactions follow secure coding practices and that no direct parameter embedding occurs in sql operations. Updates to version 3.5.8 or later are essential as they contain the necessary patches to address this vulnerability through proper input handling and sanitization measures.
