The WP Job Portal plugin for WordPress, versions up to and including 2.2.2, contains an SQL Injection vulnerability (CWE-89) in the getFieldsForVisibleCombobox() function. The vulnerability is due to insufficient escaping and lack of proper preparation of the 'ff' parameter, which is user-supplied. Authenticated attackers with Administrator-level access can append malicious SQL commands to existing queries, potentially extracting sensitive database information. The CVSS 3.1 base score is 4.9 (medium severity) with network attack vector, low attack complexity, and high privileges required. No patch or vendor advisory is currently available.

An attacker with Administrator-level access can exploit this vulnerability to perform SQL Injection attacks, enabling unauthorized extraction of sensitive data from the database. The vulnerability does not impact integrity or availability but compromises confidentiality. Since exploitation requires high privileges, the risk is limited to trusted users who have elevated access.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Administrator-level access to trusted users only and monitor for unusual database query activity related to the 'ff' parameter. Avoid using vulnerable plugin versions in production environments.
