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 Stylemix uListing ulisting allows Object Injection.This issue affects uListing: from n/a through <= 2.2.0.

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

This is a PHP Object Injection vulnerability in the Stylemix uListing WordPress plugin. The plugin uses PHP's unserialize() function on untrusted user-supplied data, allowing remote attackers to instantiate arbitrary PHP objects. By leveraging available 'gadget chains' (existing classes with magic methods), attackers can potentially achieve remote code execution, file operations, or other malicious activities.

MitigationUpdate uListing to the latest version which should replace unsafe unserialize() calls with json_decode() or implement proper input validation. If no update is available, disable the plugin until a patch is released.

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 uListing plugin is installed
    Locate the uListing plugin directory in your WordPress installation (typically wp-content/plugins/ulisting) and confirm the plugin files exist
    Affected if The uListing plugin files are present on the server
  2. Determine the installed uListing version
    Open the main plugin file (usually ulisting.php) and locate the version comment in the file header, or check the plugin version displayed in WordPress admin under Plugins
    Affected if The installed version is older than the patched version that replaces unserialize() with json_decode()
  3. Confirm the plugin is active
    In WordPress admin, navigate to Plugins > Installed Plugins and verify whether uListing is activated
    Affected if The plugin is currently active and processing requests
  4. Check for vulnerable unserialize calls
    Review plugin source code for use of unserialize() function on user-supplied input (typically $_POST, $_GET, or $_REQUEST parameters)
    Affected if Code contains unserialize() calls handling untrusted input without prior validation
  5. Inspect server access logs
    Review HTTP access logs for unusual requests to uListing endpoints that may indicate exploitation attempts, particularly POST requests with serialized PHP object data
    Affected if Logs show requests containing serialized PHP data being sent to uListing endpoints

Your environment is affected if the uListing plugin is installed, active, uses an older version containing unsafe unserialize() calls on user input, and those unserialize() paths are reachable via web requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update uListing to the latest version which should replace unsafe unserialize() calls with json_decode() or implement proper input validation. If no update is available, disable the plugin until a patch is released.
