## Technical details

A Blind SQL Injection vulnerability exists in the Easy Form Builder plugin (versions up to and including 4.0.6) due to improper neutralization of special elements used in SQL commands (CWE-89). The flaw allows an unauthenticated attacker to send crafted requests to the server and infer data from the database based on the application's response patterns. This is a network-based attack that requires no user interaction or prior authentication. Successful exploitation can lead to high confidentiality impact and a partial impact on availability. Users are advised to update to a version newer than 4.0.6 if available.
