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 RealMag777 TableOn posts-table-filterable allows Object Injection.This issue affects TableOn: from n/a through <= 1.0.4.3.

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

The TableOn WordPress plugin <= 1.0.4.3 contains a PHP Object Injection vulnerability via unsafe deserialization of user-supplied data in the posts-table-filterable component. An unauthenticated attacker can exploit this by sending crafted serialized PHP objects, potentially achieving remote code execution if vulnerable classes exist in the plugin or theme ecosystem.

MitigationUpgrade TableOn to the latest version immediately. If patching is not possible, disable the plugin until an update is available. Review and audit surrounding code for other deserialization endpoints.

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 TableOn plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for TableOn, or check the /wp-content/plugins/ directory for a folder named 'wp-table-on' or similar TableOn-related folders.
    Affected if TableOn plugin is present in the WordPress installation
  2. Determine installed TableOn version
    Check the plugin header in /wp-content/plugins/tableon/plugin.php (or main plugin file) for the 'Version' comment, or view the plugin details in WordPress admin Plugins page.
    Affected if The version number is 1.0.4.3 or lower (any version up to and including 1.0.4.3)
  3. Confirm posts-table-filterable component is accessible
    Inspect the plugin files for the posts-table-filterable component. Look for files handling this feature, typically in classes or includes directories. Check if the component handles serialized data via $_POST, $_GET, or $_REQUEST parameters.
    Affected if The component processes user-supplied data without proper sanitization and uses unsafe deserialization functions like unserialize()
  4. Check for vulnerable class dependencies
    Audit the plugin and active theme for classes that could be chained for object injection (common examples include __wakeup, __destruct, or __toString magic methods). Search plugin/theme code for class definitions that could be exploited.
    Affected if Vulnerable classes exist in the plugin, theme, or other installed plugins that could be leveraged for code execution via the deserialization flaw

A user is affected if TableOn plugin is installed with version 1.0.4.3 or lower and the posts-table-filterable component processes user-supplied serialized data without validation.
