## Technical details

A Blind SQL Injection vulnerability exists in the Funnel Builder by FunnelKit plugin for WordPress due to improper neutralization of special elements used in SQL commands (CWE-89). The flaw is present in versions up to and including 3.15.0.5. An attacker with high privileges (such as an Administrator) can exploit this over the network without user interaction to extract sensitive information from the site's database. While the CVSS score is high (7.6) due to the potential for data exfiltration, the requirement for administrative privileges reduces the likelihood of exploitation by external actors. The issue is resolved in version 3.15.0.6.
