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

Reflected XSS vulnerability in the Contest Gallery WordPress plugin allows unauthenticated attackers to inject malicious JavaScript code via unsanitized user input that gets reflected in web pages without proper output encoding.

MitigationFix requires implementing proper input validation and context-aware output encoding on all user-supplied parameters throughout the plugin, particularly in pages handling contest submissions and gallery displays.

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 Contest Gallery plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Contest Gallery', or check if the /wp-content/plugins/contest-gallery/ directory exists on the server
    Affected if The plugin is present and active in the WordPress installation
  2. Identify installed version
    In WordPress admin, view the plugin details from the Plugins list to see the version number, or open the main plugin PHP file and check the 'Version' header in the plugin comment block
    Affected if The installed version is lower than 24.0.4 (for example, 24.0.3, 24.0.2, or earlier)
  3. Verify contest submission pages are accessible
    Visit pages on the site that contain contest submission forms or gallery displays. These are the areas where user input gets reflected. Check the frontend for any publicly accessible contest or gallery pages
    Affected if Publicly accessible contest submission or gallery display pages exist that accept user input
  4. Review access logs for XSS indicators
    Examine web server access logs (Apache, Nginx) or WordPress audit logs for unusual request parameters containing script tags, javascript:, or event handlers (onload, onerror, onclick) in URLs pointing to contest or gallery pages
    Affected if Log entries show attempts to inject malicious script content via URL parameters on contest/gallery pages

The environment is affected if the Contest Gallery plugin is installed with a version lower than 24.0.4 and publicly accessible contest submission or gallery pages exist that could reflect unsanitized user input.
