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
Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Yannick Lefebvre Link Library allows Reflected XSS.This issue affects Link Library: from n/a through 7.7.1.

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 · moderate confidence

A reflected XSS vulnerability exists in the Link Library WordPress plugin due to improper neutralization of user-supplied input during web page generation. Attackers can inject malicious scripts through unsanitized parameters that get reflected in the response, potentially stealing session cookies or performing actions on behalf of authenticated users.

MitigationUpdate Link Library to the latest patched version once available. Until then, implement output encoding and input validation on all user-supplied parameters, and consider deploying a WAF rule to block XSS attack patterns.

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. Locate Link Library plugin installation
    Check the WordPress plugins directory (wp-content/plugins/link-library) or use WP-CLI: wp plugin list --name='link-library'
    Affected if The plugin is installed and the directory exists
  2. Determine installed version
    Read the main plugin file header (link-library.php) for 'Version:' value, or run: wp plugin get link-library --field=version
    Affected if Version is less than 7.7.2
  3. Confirm plugin is active
    Run: wp plugin is-active link-library, or check WordPress admin Plugins page
    Affected if Plugin is active and version is < 7.7.2
  4. Identify exposed query parameters
    Review the plugin code for $_GET, $_POST, or $_REQUEST usage that outputs to HTML without sanitization (look for echo, print, or printf calls with unsanitized variables)
    Affected if Plugin processes and reflects user input in responses without proper encoding

You are affected if Link Library plugin is installed, active, and running a version lower than 7.7.2, with unsanitized parameters being reflected in web page output.

Upgrade available Upgrade to 7.7.2 or later
Fixed in 7.7.2
Interim mitigation

Update Link Library to the latest patched version once available. Until then, implement output encoding and input validation on all user-supplied parameters, and consider deploying a WAF rule to block XSS attack patterns.

Recommended fix High confidence

7.7.2

  1. 1. Backup your WordPress site database and files before making any changes
  2. 2. Navigate to Plugins > Installed Plugins in the WordPress admin dashboard
  3. 3. Locate 'Link Library' in the plugin list
  4. 4. Check the current version number to confirm it is 7.7.1 or earlier (vulnerable)
  5. 5. Click 'Update now' if an update to 7.7.2 is available, or manually download version 7.7.2 from the WordPress plugin repository
  6. 6. After updating, verify the new version number displays as 7.7.2
  7. 7. Test that Link Library functionality works correctly on your site
