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
The WP Job Portal plugin for WordPress is vulnerable to SQL Injection via the 'radius' parameter in all versions up to, and including, 2.4.8 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

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 · high confidence

The WP Job Portal WordPress plugin (versions up to 2.4.8) contains an unauthenticated SQL injection vulnerability in the 'radius' parameter. The plugin fails to properly escape user input and does not use prepared statements, allowing attackers to inject arbitrary SQL queries and potentially extract sensitive data from the database.

MitigationUpgrade to version 2.4.9 or later which contains the fix. Until then, consider disabling the plugin or implementing WAF rules to block SQL injection attempts targeting the 'radius' parameter.

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 WP Job Portal plugin is installed
    Check for the plugin directory at wp-content/plugins/wp-job-portal/ or look for the plugin in WordPress admin under Plugins > Installed Plugins
    Affected if Plugin is not present in the installation
  2. Check installed plugin version
    View the plugin version in the plugin header (wp-content/plugins/wp-job-portal/wp-job-portal.php) or in the plugin's readme.txt file under the 'Stable tag' field
    Affected if Version is 2.4.8 or lower
  3. Identify the radius parameter endpoint
    Locate the PHP file(s) handling the 'radius' parameter search functionality - typically in the job search or location-based query handlers within the plugin's includes or controller folders
    Affected if The radius parameter feature exists and processes user input
  4. Verify SQL query lacks prepared statements
    Open the identified file handling the radius parameter and inspect the database query code - look for direct use of $_REQUEST['radius'] or similar in SQL statements without $wpdb->prepare() or proper escaping
    Affected if The radius parameter is used in raw SQL queries without $wpdb->prepare() or parameterized queries

You are affected if WP Job Portal plugin version is 2.4.8 or lower AND the radius parameter feature is accessible/used in your environment with SQL queries that lack prepared statements.

Mitigation

Upgrade to version 2.4.9 or later which contains the fix. Until then, consider disabling the plugin or implementing WAF rules to block SQL injection attempts targeting the 'radius' parameter.
