Deeper analysis

The Business Directory Plugin for WordPress, also known as Easy Listing Directories, is affected by a time-based SQL injection vulnerability in all versions through 6.4.2. The flaw exists in the ‘listingfields’ parameter because of insufficient escaping of user-supplied input and missing prepared-statement handling on an existing SQL query, corresponding to CWE-89 and carrying a CVSS 3.1 score of 9.8.

Unauthenticated attackers can supply a crafted ‘listingfields’ value over the network to append arbitrary SQL to backend queries. Successful exploitation allows extraction of sensitive information from the database and may extend to modification or deletion of data given the complete confidentiality, integrity, and availability impact.

Public references include Wordfence advisory details and WordPress plugin repository changesets that document the corrective code committed after disclosure. The associated EPSS score remains near its peak of 0.9399 with a current value of 0.9387, indicating sustained exploitation interest since publication.
