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
Unauthenticated Cross Site Scripting (XSS) in Modula - PRO <= 2.10.8 versions.

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.

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 Modula-PRO plugin installation
    Access WordPress admin dashboard, navigate to Plugins > Installed Plugins, and locate Modula-PRO in the list. The version number is displayed directly on this page.
    Affected if Modula-PRO plugin is present in the WordPress installation
  2. Retrieve exact plugin version number
    If not visible on plugins page, access via FTP or file manager, navigate to /wp-content/plugins/modula-pro/ and open the main plugin file (usually modula-pro.php or similar) to read the version header comment.
    Affected if Version retrieved is 2.10.8 or lower
  3. Compare version against affected range
    Compare the installed version number to the affected range. The plugin follows semantic versioning; any version 2.10.8 or lower (including 2.10.7, 2.10.6, etc.) falls within the vulnerable range.
    Affected if Installed version is 2.10.8 or any version number lower than 2.10.8
  4. Verify public plugin endpoints are accessible
    Check that the Modula-PRO plugin is active and its shortcodes or public-facing features are in use on the site. This can be confirmed by searching the codebase for modula_pro shortcode usage or by accessing known public URLs.
    Affected if Plugin is active and exposed via WordPress frontend
  5. Confirm plugin is reachable without authentication
    Test that unauthenticated users can access the vulnerable plugin functionality. This can be done by viewing published galleries or using the plugin shortcodes as a non-logged-in visitor.
    Affected if Plugin functionality is accessible to unauthenticated (logged-out) users

If Modula-PRO plugin is installed with version 2.10.8 or lower and is accessible to unauthenticated users on the WordPress site, the environment is affected by CVE-2026-57426.
