NVD · unedited

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 vulnerability in the ThemeHigh Job Manager & Career WordPress plugin combines Cross-Site Request Forgery (CSRF) with Deserialization of Untrusted Data. The CSRF weakness allows attackers to trick authenticated administrators into submitting unintended requests, while the unsafe deserialization could enable PHP object injection leading to arbitrary code execution if vulnerable classes are present on the target system.

MitigationUpdate the plugin to the latest version immediately. If no patched version is available, disable the plugin until a fix is released. Implement CSRF tokens/nonces on all state-changing forms andAJAX actions, and remove or secure any use of unserialize() with user-controlled data.

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 plugin installation status
    Check if the Themehigh Job Manager & Career plugin is installed in your WordPress environment. Navigate to WP Admin > Plugins or inspect the /wp-content/plugins/ directory for a folder named 'job-manager-career' or similar.
    Affected if The plugin is not installed on the WordPress site.
  2. Identify installed plugin version
    In WordPress admin, go to Plugins > Plugin Editor or check the plugin's main PHP file header for the 'Version' field. Alternatively, read the version from the plugin's readme.txt or main plugin file.
    Affected if The installed version is 1.4.4 or lower.
  3. Confirm plugin is active
    Check if the plugin is currently activated in your WordPress site by querying the wp_options table for the active_plugins option, or view the Plugins page in admin panel.
    Affected if The plugin is active and running a vulnerable version.
  4. Inspect for unserialize() usage in plugin code
    Search the plugin directory for uses of unserialize() function by reviewing the plugin's PHP files, particularly AJAX handlers and form processing code.
    Affected if The plugin code contains unserialize() handling user-supplied data without proper validation.
  5. Review AJAX actions for state-changing operations
    Examine the plugin's registered AJAX actions (look for wp_ajax_ hooks in the code) to identify endpoints that process serialized data or accept user-controlled input.
    Affected if AJAX actions accept and unserialize data without nonce/token validation.

Your environment is affected if the Themehigh Job Manager & Career plugin is installed, active, and running version 1.4.4 or lower with unserialize() handling user input in AJAX or form handlers.

Upgrade available Upgrade to a release after 1.4.4
Interim mitigation
