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 artbees JupiterX Core jupiterx-core allows Object Injection.This issue affects JupiterX Core: from n/a through <= 4.10.1.

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

A deserialization vulnerability in the artbees JupiterX Core WordPress plugin (versions through 4.10.1) allows unauthenticated attackers to inject malicious PHP objects through untrusted data, potentially leading to remote code execution.

MitigationUpdate JupiterX Core to the latest patched version once available. If no patch exists, implement web application firewall rules to block deserialization-related payloads and consider disabling the plugin until a fix 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. Confirm JupiterX Core plugin is installed
    Log in to WordPress admin and navigate to Plugins > Installed Plugins, or check the /wp-content/plugins/jupiterx-core/ directory via file system. Look for 'JupiterX Core' in the list.
    Affected if Plugin is present on the WordPress installation
  2. Check installed version number
    In WordPress admin, find JupiterX Core in the plugin list and read the version number displayed below the plugin name. Alternatively, open /wp-content/plugins/jupiterx-core/readme.txt and locate the 'Stable tag' or check the plugin header in /wp-content/plugins/jupiterx-core/jupiterx-core.php for 'Version:'
    Affected if Version is 4.10.1 or lower (any version through 4.10.1)
  3. Verify plugin is active
    In WordPress admin > Plugins, confirm JupiterX Core shows as 'Active' (not just installed). If using WP-CLI, run: wp plugin status jupiterx-core
    Affected if Plugin is active and processing requests
  4. Check for signs of exploitation
    Review web server access logs for suspicious deserialization payloads (look for serialized PHP objects containing patterns like 'O:', 'a:', 'C:', etc.). Check /wp-content/uploads/ and /wp-content/plugins/jupiterx-core/ for newly created suspicious PHP files with encoded content.
    Affected if Log evidence of deserialization attacks or unexpected PHP files exist in plugin directories

If JupiterX Core plugin version 4.10.1 or lower is installed and active, the environment is affected by this deserialization vulnerability.
