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 · uneditedThe Link Library WordPress plugin before 7.9.3 does not properly sanitise and escape a user-supplied value before using it in a SQL query, allowing unauthenticated users to perform SQL injection attacks.
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 confidenceThe Link Library WordPress plugin before version 7.9.3 contains a critical SQL injection vulnerability. The plugin fails to properly sanitize and escape user-supplied input before using it in SQL queries, allowing unauthenticated attackers to inject arbitrary SQL commands and potentially exfiltrate or modify database contents.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate the Link Library plugin filesCheck the WordPress plugins directory at wp-content/plugins/link-library/ for the existence of the plugin folder, or look for 'Link Library' in the WordPress admin under Plugins > Installed Plugins.Affected if The plugin folder exists and the plugin is active in WordPress.
-
Identify the installed versionOpen the main plugin file (typically link-library.php) and look for the version comment header, or check the readme.txt file for the 'Stable tag' entry.Affected if The version number returned is lower than 7.9.3 (e.g., 7.9.2, 7.9.1, 7.9.0, or earlier).
-
Confirm plugin is accessible to visitorsVerify the plugin is not disabled and that its functionality is exposed to unauthenticated users. Since this is a link directory plugin, public-facing pages using its shortcode or widget are typically accessible without login.Affected if The plugin is active and its features are accessible to non-logged-in users (the default configuration).
If the Link Library plugin is installed, active, and running at a version lower than 7.9.3 with public-facing functionality, the environment is vulnerable to unauthenticated SQL injection.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate the Link Library WordPress plugin to version 7.9.3 or later immediately. If immediate updating is not feasible, consider disabling the plugin or deploying a WAF rule to block SQL injection attack patterns.
Link Library plugin version 7.9.3 or later
- Backup the WordPress site and database before performing any updates
- Navigate to the WordPress admin dashboard, go to Plugins > Installed Plugins
- Find the Link Library plugin and click 'Update now' to install version 7.9.3 or later
- Alternatively, use WP-CLI: wp plugin update link-library
- Verify the installed version is 7.9.3 or later by checking the plugin version in the plugins list
- Test that the plugin functionality works correctly after the update
