Deeper analysis

The vulnerability is a PHP Local File Inclusion flaw stemming from improper control of filenames in include/require statements, tracked as CWE-98. It affects the Calculator Builder plugin for WordPress developed by Wow-Company, with all versions through 1.6.2 impacted.

An unauthenticated remote attacker can exploit the issue over the network, though successful exploitation requires high attack complexity and user interaction. If leveraged, the flaw permits local file inclusion that can result in high impact to confidentiality, integrity, and availability on the affected site.

The sole reference points to a Patchstack advisory entry that catalogs the WordPress plugin vulnerability and its affected versions. The EPSS score remains low, with a recorded peak of only 0.0115.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
Why these techniques?

The LFI vulnerability in a public-facing WordPress plugin directly enables exploitation of public-facing applications via T1190. It also facilitates data collection from the local system (T1005) by allowing inclusion of sensitive files, potentially leading to disclosure or further impacts as described.
