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
Contributor SQL Injection in wpForo Forum <= 3.0.9 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.

dbcve analysis · moderate confidence

SQL injection vulnerability in wpForo Forum plugin for WordPress versions 3.0.9 and below. The flaw allows authenticated users with contributor-level permissions to inject malicious SQL queries through unsanitized input parameters, potentially enabling unauthorized data access or database manipulation.

MitigationUpdate wpForo Forum plugin to a version newer than 3.0.9. If no update is available, disable the plugin until a patched version is released, or implement input sanitization/parameterized queries in the affected code paths.

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. Identify if wpForo Forum plugin is installed
    In WordPress admin dashboard, go to Plugins > Installed Plugins and look for 'wpForo Forum' in the list, or inspect the file system at /wp-content/plugins/ for a folder containing 'wpforo'.
    Affected if The plugin is present in the WordPress installation
  2. Determine the installed wpForo version
    In WordPress admin, go to Plugins > Installed Plugins and locate wpForo Forum. The version number is displayed below the plugin name. Alternatively, check the main plugin file header in /wp-content/plugins/wpforo/ for the 'Version' comment.
    Affected if The version is 3.0.9 or lower
  3. Verify if contributor-level user accounts exist
    In WordPress admin, go to Users and review the role assigned to each user. Contributor role is visible in the Users list table under the Role column.
    Affected if At least one user with Contributor role (or higher roles that include contributor permissions) exists on the site
  4. Check for anomalous database query patterns in logs
    Review WordPress debug logs (wp-content/debug.log if logging is enabled) and server access/error logs for SQL syntax patterns, UNION SELECT statements, or unexpected database queries originating from wpForo endpoints.
    Affected if Suspicious SQL patterns appear in logs with wpForo-related request paths

A user is affected if wpForo Forum plugin versions 3.0.9 or below are installed AND at least one authenticated user with contributor-level permissions exists on the WordPress site.
