Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the improper control of filenames in PHP include/require statements by requiring validation and sanitization of inputs to prevent local file inclusion.
Requires timely remediation of identified flaws, directly addressing the PHP LFI vulnerability in the SevenTrees WordPress theme through patching.
Establishes secure configuration settings for PHP and web servers, such as open_basedir restrictions, to limit arbitrary local file access attempts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Exploits public-facing WordPress theme vulnerability (T1190) via LFI, enabling direct access to local files (T1005) and unsecured credentials in files such as wp-config.php (T1552.001).

Deeper analysisAI
CVE-2026-22364 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98, that enables PHP Local File Inclusion in the SevenTrees WordPress theme developed by axiomthemes. The issue affects all versions of the theme up to and including 1.0.2. Published on 2026-02-20, it 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 high severity due to its potential for significant impact on confidentiality, integrity, and availability.
A remote attacker with no required privileges or user interaction can exploit this vulnerability over the network, though it demands high attack complexity. Successful exploitation allows inclusion of arbitrary local files on the server, potentially leading to unauthorized access to sensitive data, code execution if exploitable local files are targeted, or disruption of system availability.
