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
A SQLi vulnerability in Komento component 4.0.0-4.0.7for Joomla was discovered. The issue allows unprivileged users to execute arbitrary SQL commands.

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 SQL injection vulnerability exists in the Komento component for Joomla versions 4.0.0 through 4.0.7. The flaw allows unprivileged users (potentially unauthenticated attackers) to inject and execute arbitrary SQL commands via unsanitized input parameters in the component, leading to complete database compromise.

MitigationUpdate Komento to the latest patched version beyond 4.0.7. If immediate patching is not possible, disable the Komento component until the update can be applied.

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. Confirm Komento component installation
    In the Joomla administrator panel, navigate to Components > Komento. If the menu item exists, Komento is installed. Alternatively, query the #__extensions table in the Joomla database for rows where element = 'com_komento'.
    Affected if Komento component is present in the Joomla installation
  2. Determine installed Komento version
    In the Joomla administrator panel, go to Components > Komento > Dashboard (or similar About page) to view the installed version number. Alternatively, locate the manifest XML file in /administrator/components/com_komento/komento.xml and read the <version> tag.
    Affected if Version cannot be determined or is not visible
  3. Compare version against vulnerable range
    Take the installed version number identified in the previous step and compare it to the affected range: 4.0.0 through 4.0.7 inclusive.
    Affected if Installed version falls between 4.0.0 and 4.0.7 inclusive (any build or sub-version within this range)
  4. Verify component accessibility
    Determine if the Komento component is exposed to unauthenticated users. In Joomla access levels, check if Komento or its public-facing features (comments, posting) are set to Public or Guest access. Alternatively, attempt to access Komento endpoints without logging in.
    Affected if Komento features are accessible to unauthenticated or guest-level users
  5. Review for indicators of compromise
    Examine the Joomla database for suspicious entries in Komento-related tables (such as #__komento_comments or #__komento_posts). Look for unusual SQL syntax, encoded characters, or unexpected data in content fields. Also review Joomla error logs and server access logs for SQL error messages referencing Komento.
    Affected if Suspicious SQL-like content found in Komento database tables or SQL errors in logs involving Komento queries

Your environment is affected if Komento is installed with version 4.0.0 through 4.0.7 and the component or its public features are accessible to unauthenticated users.
