Vulnerability Overview

The DeBounce Email Validator plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 5.7. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

Technical Analysis

REMEDIATION: Update to version 5.71, or a newer patched version --- IDENTIFIER: CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')) The PHP application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in require, include, or similar functions.
