Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Attackers can exploit this to extract arbitrary data from the database, including user password hashes.

MitigationUpdate the Library Management System plugin to version 3.5.8 or later to remediate the SQL injection vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Library Management System plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Library Management System' or check the plugins directory via FTP/file manager for /wp-content/plugins/library-management-system/
    Affected if The plugin is not found or not installed
  2. Check the installed plugin version
    In WordPress admin Plugins list, click on the plugin name to view details and locate the version number, or read the main plugin file header in /wp-content/plugins/library-management-system/
    Affected if The version shown is lower than 3.5.8 (for example, 3.5.7, 3.5.6, etc.)
  3. Confirm plugin is active
    In WordPress admin Plugins list, verify the plugin shows as 'Active' rather than 'Inactive' or 'Must-Use'
    Affected if The plugin is active and version is below 3.5.8
  4. Verify unauthenticated access is possible
    The vulnerability is unauthenticated, meaning it can be exploited without logging in. Check that the plugin pages/endpoints are publicly accessible (not restricted by firewall, authentication plugins, or server configuration)
    Affected if The plugin is publicly accessible without authentication

You are affected if the Library Management System plugin is installed, active, and the version is below 3.5.8, with no external protection blocking unauthenticated access to the plugin.
