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 · high confidence

This is a PHP Object Injection vulnerability in the TF Woo Product Grid Addon For Elementor WordPress plugin. The vulnerability stems from unsafe deserialization (likely PHP unserialize()) of untrusted data, allowing remote attackers to inject malicious PHP objects. Depending on available 'gadget chains' in the WordPress environment, this could lead to remote code execution, file operations, or privilege escalation.

MitigationUpdate the plugin to the latest version once a patch is released; if no patch is available, deactivate and remove the plugin. Ensure the WordPress environment is not exposed to unauthenticated attackers in the interim.

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 TF Woo Product Grid Addon plugin is installed
    Navigate to WordPress admin > Plugins, or inspect the wp-content/plugins directory for a folder containing 'tf-woo-product-grid' or similar naming. Confirm the plugin files are present.
    Affected if The plugin is installed and active in the WordPress environment.
  2. Determine the installed plugin version
    Open the main plugin PHP file (often in the plugin root) and locate the version comment or header (e.g., 'Version: 1.0.1'). Alternatively, check the Plugins admin page in WordPress for the listed version number.
    Affected if The reported version is 1.0.1 or lower.
  3. Identify if the plugin exposes AJAX or public endpoints
    Review the plugin source code for action hooks (add_action) targeting 'wp_ajax_*' or 'wp_ajax_nopriv_*' actions, or any REST API endpoints. These are common vectors for deserialization input.
    Affected if The plugin processes serialized data through AJAX or public-facing hooks without validation.
  4. Check server access logs for suspicious deserialization activity
    Review web server access logs (Apache/Nginx) for requests to the plugin's AJAX endpoints containing serialized PHP objects (look for patterns like 'O:','a:','s:'). Also check for any recent unauthorized code execution indicators.
    Affected if Logs show deserialized data being processed or signs of exploitation attempts.

A user is affected if the TF Woo Product Grid Addon plugin is installed with version 1.0.1 or lower and the vulnerable deserialization handler is accessible.
