Deeper analysis
CVE-2026-28028 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as PHP Remote File Inclusion but enabling PHP Local File Inclusion, in the ThemeREX MoneyFlow WordPress theme. This flaw affects all versions of MoneyFlow up to and including 1.0. Mapped to CWE-98, it stems from inadequate sanitization of filenames used in PHP include/require statements, allowing attackers to manipulate file paths.
The vulnerability carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating exploitation over the network by unauthenticated attackers (PR:N) with no user interaction required (UI:N), though it demands high attack complexity (AC:H). Successful exploitation could grant high-impact confidentiality, integrity, and availability consequences, potentially enabling attackers to include and execute arbitrary local files on the server, leading to sensitive data exposure, server-side code execution, or full system compromise depending on server configuration and accessible files.
Patchstack advisories document this local file inclusion vulnerability in the WordPress MoneyFlow theme version 1.0, providing details on the issue via their database entry.
