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 Contest Gallery <= 30.0.0 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 the Contest Gallery WordPress plugin (versions <= 30.0.0) allows authenticated users with Contributor-level permissions to inject malicious SQL queries through unsanitized input parameters, potentially enabling unauthorized data exfiltration or database manipulation.

MitigationUpdate Contest Gallery plugin to a version beyond 30.0.0 when available, or apply vendor-supplied security patches; alternatively, restrict or disable the plugin until remediation is possible.

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. Verify Contest Gallery plugin installation and version
    In WordPress admin, go to Plugins > Installed Plugins and locate Contest Gallery. Check the version number displayed under the plugin name. Alternatively, check the plugin's main PHP file header or version.php for the version constant.
    Affected if The installed version is 30.0.0 or lower.
  2. Confirm plugin is active
    In WordPress admin under Plugins > Installed Plugins, verify that Contest Gallery shows as 'Active' rather than 'Inactive'.
    Affected if The plugin is active and version is 30.0.0 or lower.
  3. Identify exposed contest gallery functionality
    Check pages, posts, or widgets containing Contest Gallery shortcodes (commonly [contest_gallery], [cg_...], or custom contest IDs). Search database wp_postmeta for meta_key containing 'contest' or review published content with gallery contests.
    Affected if Contest Gallery shortcodes or forms are published and accessible to logged-in users.
  4. Audit user role permissions
    In WordPress admin under Users, review which users have the Contributor role. Also check if any custom roles with similar capabilities exist. Contributors can create and edit posts but cannot publish.
    Affected if One or more users have Contributor-level permissions, and they can access contest gallery functionality.
  5. Inspect plugin input handling (optional)
    If you have file access, examine the plugin source code for $_GET, $_POST, or $_REQUEST usage in contest-related files without proper prepare() statements or sanitization functions like esc_sql() or $wpdb->prepare().
    Affected if Unsanitized input parameters are present in contest-related code.

Your environment is likely affected if Contest Gallery plugin version 30.0.0 or lower is active and you have Contributor-level users who can access contest functionality that accepts user input.
