DescriptionCVE.org

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.

AnalysisAI

SQL injection in the Library Management System WordPress plugin before 3.5.8 lets unauthenticated attackers inject arbitrary SQL through an unsanitized request parameter and read data straight from the WordPress database, including user password hashes. Publicly available exploit code exists and the flaw was reported by WPScan, though the EPSS probability is low (0.18%, 7th percentile) and it is not on CISA KEV. The vendor has shipped a fixed release (3.5.8), making patching the clear priority for affected sites.

Technical ContextAI

The affected component is a third-party WordPress plugin (CPE cpe:2.3:a:unknown:library_management_system) that adds library catalog/loan management functionality to WordPress sites. The root cause is a classic SQL injection (CWE-89, though the input lists CWE as N/A): a user-supplied parameter is concatenated into a SQL statement without sanitization or escaping/parameterization. Because WordPress plugins run queries against the shared site database via the global $wpdb layer, one injectable query exposes not just plugin tables but the entire schema - notably wp_users, where password hashes and emails are stored.

RemediationAI

Vendor-released patch: version 3.5.8 - upgrade the Library Management System plugin to 3.5.8 or later, which is the definitive fix. Until the update is applied, restrict exposure by placing a WAF/virtual-patch rule in front of WordPress to block SQL-injection patterns on the plugin's request parameters (trade-off: rule tuning may cause false positives and is not a substitute for the patch), or temporarily deactivate the plugin if library functionality is non-critical (trade-off: removes the feature entirely). Because password hashes may already have been exposed on internet-facing sites, force a password reset for all WordPress users and rotate secrets after patching. See the WPScan advisory (https://wpscan.com/vulnerability/762dd8c3-8972-46ef-90c2-9f3f5dce4370/) for details.
