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
Deserialization of Untrusted Data vulnerability in BoldGrid weForms weforms allows Object Injection.This issue affects weForms: from n/a through <= 1.6.26.

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

PHP Object Injection vulnerability in BoldGrid weForms plugin allows remote attackers to inject malicious PHP objects via unsafe deserialization of untrusted data. This can lead to remote code execution if suitable 'gadget chains' (existing classes in the application or WordPress ecosystem) are present.

MitigationUpgrade weForms to the latest version immediately. If no patch is available, disable the plugin until a fix is released, and implement web application firewall rules to block serialized object payloads.

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 weForms plugin is installed
    Log into WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'weForms' or 'BoldGrid weForms' in the list. Alternatively, check the /wp-content/plugins/ directory for the weforms folder.
    Affected if weForms plugin is present and active in the WordPress installation
  2. Identify installed weForms version
    In WordPress admin, click on the weForms plugin entry to view details, which typically displays the version number. Alternatively, open the main plugin file (usually weforms.php) in /wp-content/plugins/weforms/ and look for the 'Version' header in the plugin comment block.
    Affected if The installed version is lower than the patched version released after this CVE (the exact version number should be obtained from BoldGrid's security advisory)
  3. Verify plugin handles form submission data
    Check if weForms is configured to accept and process form submissions. In the WordPress admin, navigate to weForms > All Forms and verify at least one form exists and is published. The vulnerability requires the plugin to be actively processing form data.
    Affected if weForms is active and processing form submissions on the site
  4. Inspect for unsafe deserialization patterns
    If you have file access, search the weForms plugin files for unserialize() function calls. Common locations include class files in /wp-content/plugins/weforms/includes/. Use grep or similar: grep -r "unserialize" /wp-content/plugins/weforms/
    Affected if The plugin code contains unserialize() calls handling untrusted input without proper sanitization

Your environment is affected if weForms plugin is installed and active with a version prior to the patched release, and the plugin processes user-submitted form data containing serialized PHP objects.
