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.

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 ARPrice WordPress plugin contains a deserialization vulnerability where untrusted data is passed to PHP's unserialize() function, allowing unauthenticated attackers to inject malicious PHP objects. This can lead to remote code execution, file operations, or other attacks depending on available gadget chains in the WordPress environment.

MitigationImmediately update to the latest patched version of ARPrice. If no patch is available, disable or remove the plugin until a fix is released. Implement proper input validation and replace unsafe deserialization with safer alternatives like JSON decoding.

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. Locate ARPrice plugin installation
    Check if the ARPrice plugin directory exists in your WordPress installation at wp-content/plugins/arprice/ (or similar naming convention). Use a file manager or find command to search for 'arprice' directories.
    Affected if The plugin directory exists in wp-content/plugins/.
  2. Identify installed plugin version
    Open the main ARPrice plugin PHP file (commonly arprice.php or index.php inside the plugin folder) and locate the version string in the plugin header comment block (e.g., 'Version: x.x.x'). Note this version number.
    Affected if A version number is found in the plugin header.
  3. Compare version to affected releases
    Cross-reference the identified version number against the official vulnerability disclosure for CVE-2024-49688 to determine if your installed version falls within affected releases. If you cannot obtain the official affected version list, treat all versions as potentially affected.
    Affected if Your installed version matches a version range publicly listed as vulnerable to CVE-2024-49688.
  4. Verify plugin is active
    In the WordPress admin dashboard, navigate to Plugins > Installed Plugins and confirm whether ARPrice is currently activated. Alternatively, query the WordPress options table for the active_plugins option.
    Affected if The ARPrice plugin shows as 'Active' in WordPress.
  5. Check for unauthenticated access to vulnerable endpoint
    Review your web server logs (access logs) for unusual or repeated HTTP requests to ARPrice-related PHP files, particularly those handling serialized data or AJAX endpoints. Use grep to search for requests to paths containing 'arprice' and ' unserialize ' patterns in logs.
    Affected if Suspicious requests targeting ARPrice deserialization endpoints appear in logs, or the plugin exposes AJAX or front-facing PHP handlers accessible without authentication.

Your environment is affected if the ARPrice plugin is installed, active, and your installed version matches a version known to be vulnerable to CVE-2024-49688 deserialization attacks.
